Fix Non-square Radiance/RGBE/.hdr images failing to load

The HDR QImageIOHandler plugin only supports the default image orientation (-Y +X) in .hdr files. It mixes up the width and height however, resulting in non-square images not loading. This fix adds a check for the standard image orientation in the file and returns false (with error message) if that fails. If it succeeds, it takes the height from the -Y component, and the width from the +X component, resulting in successful loading of the image. Add autotest images for landscape and portrait HDR (Radiance RGBE) loader BUGS: 433877

                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 2.1, February 1999
 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 	51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 [This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]
                            Preamble
  The licenses for most software are designed to take away your
 freedom to share and change it.  By contrast, the GNU General Public
 Licenses are intended to guarantee your freedom to share and change
 free software--to make sure the software is free for all its users.
  This license, the Lesser General Public License, applies to some
 specially designated software packages--typically libraries--of the
 Free Software Foundation and other authors who decide to use it.  You
 can use it too, but we suggest you first think carefully about whether
 this license or the ordinary General Public License is the better
 strategy to use in any particular case, based on the explanations
 below.
  When we speak of free software, we are referring to freedom of use,
 not price.  Our General Public Licenses are designed to make sure that
 you have the freedom to distribute copies of free software (and charge
 for this service if you wish); that you receive source code or can get
 it if you want it; that you can change the software and use pieces of
 it in new free programs; and that you are informed that you can do
 these things.
  To protect your rights, we need to make restrictions that forbid
 distributors to deny you these rights or to ask you to surrender these
 rights.  These restrictions translate to certain responsibilities for
 you if you distribute copies of the library or if you modify it.
  For example, if you distribute copies of the library, whether gratis
 or for a fee, you must give the recipients all the rights that we gave
 you.  You must make sure that they, too, receive or can get the source
 code.  If you link other code with the library, you must provide
 complete object files to the recipients, so that they can relink them
 with the library after making changes to the library and recompiling
 it.  And you must show them these terms so they know their rights.
  We protect your rights with a two-step method: (1) we copyright the
 library, and (2) we offer you this license, which gives you legal
 permission to copy, distribute and/or modify the library.
  To protect each distributor, we want to make it very clear that
 there is no warranty for the free library.  Also, if the library is
 modified by someone else and passed on, the recipients should know
 that what they have is not the original version, so that the original
 author's reputation will not be affected by problems that might be
 introduced by others.
  Finally, software patents pose a constant threat to the existence of
 any free program.  We wish to make sure that a company cannot
 effectively restrict the users of a free program by obtaining a
 restrictive license from a patent holder.  Therefore, we insist that
 any patent license obtained for a version of the library must be
 consistent with the full freedom of use specified in this license.
  Most GNU software, including some libraries, is covered by the
 ordinary GNU General Public License.  This license, the GNU Lesser
 General Public License, applies to certain designated libraries, and
 is quite different from the ordinary General Public License.  We use
 this license for certain libraries in order to permit linking those
 libraries into non-free programs.
  When a program is linked with a library, whether statically or using
 a shared library, the combination of the two is legally speaking a
 combined work, a derivative of the original library.  The ordinary
 General Public License therefore permits such linking only if the
 entire combination fits its criteria of freedom.  The Lesser General
 Public License permits more lax criteria for linking other code with
 the library.
  We call this license the "Lesser" General Public License because it
 does Less to protect the user's freedom than the ordinary General
 Public License.  It also provides other free software developers Less
 of an advantage over competing non-free programs.  These disadvantages
 are the reason we use the ordinary General Public License for many
 libraries.  However, the Lesser license provides advantages in certain
 special circumstances.
  For example, on rare occasions, there may be a special need to
 encourage the widest possible use of a certain library, so that it
 becomes a de-facto standard.  To achieve this, non-free programs must
 be allowed to use the library.  A more frequent case is that a free
 library does the same job as widely used non-free libraries.  In this
 case, there is little to gain by limiting the free library to free
 software only, so we use the Lesser General Public License.
  In other cases, permission to use a particular library in non-free
 programs enables a greater number of people to use a large body of
 free software.  For example, permission to use the GNU C Library in
 non-free programs enables many more people to use the whole GNU
 operating system, as well as its variant, the GNU/Linux operating
 system.
  Although the Lesser General Public License is Less protective of the
 users' freedom, it does ensure that the user of a program that is
 linked with the Library has the freedom and the wherewithal to run
 that program using a modified version of the Library.
  The precise terms and conditions for copying, distribution and
 modification follow.  Pay close attention to the difference between a
 "work based on the library" and a "work that uses the library".  The
 former contains code derived from the library, whereas the latter must
 be combined with the library in order to run.
                  GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  0. This License Agreement applies to any software library or other
 program which contains a notice placed by the copyright holder or
 other authorized party saying it may be distributed under the terms of
 this Lesser General Public License (also called "this License").
 Each licensee is addressed as "you".
  A "library" means a collection of software functions and/or data
 prepared so as to be conveniently linked with application programs
 (which use some of those functions and data) to form executables.
  The "Library", below, refers to any such software library or work
 which has been distributed under these terms.  A "work based on the
 Library" means either the Library or any derivative work under
 copyright law: that is to say, a work containing the Library or a
 portion of it, either verbatim or with modifications and/or translated
 straightforwardly into another language.  (Hereinafter, translation is
 included without limitation in the term "modification".)
  "Source code" for a work means the preferred form of the work for
 making modifications to it.  For a library, complete source code means
 all the source code for all modules it contains, plus any associated
 interface definition files, plus the scripts used to control
 compilation and installation of the library.
  Activities other than copying, distribution and modification are not
 covered by this License; they are outside its scope.  The act of
 running a program using the Library is not restricted, and output from
 such a program is covered only if its contents constitute a work based
 on the Library (independent of the use of the Library in a tool for
 writing it).  Whether that is true depends on what the Library does
 and what the program that uses the Library does.
  1. You may copy and distribute verbatim copies of the Library's
 complete source code as you receive it, in any medium, provided that
 you conspicuously and appropriately publish on each copy an
 appropriate copyright notice and disclaimer of warranty; keep intact
 all the notices that refer to this License and to the absence of any
 warranty; and distribute a copy of this License along with the
 Library.
  You may charge a fee for the physical act of transferring a copy,
 and you may at your option offer warranty protection in exchange for a
 fee.
  2. You may modify your copy or copies of the Library or any portion
 of it, thus forming a work based on the Library, and copy and
 distribute such modifications or work under the terms of Section 1
 above, provided that you also meet all of these conditions:
    a) The modified work must itself be a software library.
    b) You must cause the files modified to carry prominent notices
    stating that you changed the files and the date of any change.
    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.
    d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.
    (For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)
 These requirements apply to the modified work as a whole.  If
 identifiable sections of that work are not derived from the Library,
 and can be reasonably considered independent and separate works in
 themselves, then this License, and its terms, do not apply to those
 sections when you distribute them as separate works.  But when you
 distribute the same sections as part of a whole which is a work based
 on the Library, the distribution of the whole must be on the terms of
 this License, whose permissions for other licensees extend to the
 entire whole, and thus to each and every part regardless of who wrote
 it.
 Thus, it is not the intent of this section to claim rights or contest
 your rights to work written entirely by you; rather, the intent is to
 exercise the right to control the distribution of derivative or
 collective works based on the Library.
 In addition, mere aggregation of another work not based on the Library
 with the Library (or with a work based on the Library) on a volume of
 a storage or distribution medium does not bring the other work under
 the scope of this License.
  3. You may opt to apply the terms of the ordinary GNU General Public
 License instead of this License to a given copy of the Library.  To do
 this, you must alter all the notices that refer to this License, so
 that they refer to the ordinary GNU General Public License, version 2,
 instead of to this License.  (If a newer version than version 2 of the
 ordinary GNU General Public License has appeared, then you can specify
 that version instead if you wish.)  Do not make any other change in
 these notices.
  Once this change is made in a given copy, it is irreversible for
 that copy, so the ordinary GNU General Public License applies to all
 subsequent copies and derivative works made from that copy.
  This option is useful when you wish to copy part of the code of
 the Library into a program that is not a library.
  4. You may copy and distribute the Library (or a portion or
 derivative of it, under Section 2) in object code or executable form
 under the terms of Sections 1 and 2 above provided that you accompany
 it with the complete corresponding machine-readable source code, which
 must be distributed under the terms of Sections 1 and 2 above on a
 medium customarily used for software interchange.
  If distribution of object code is made by offering access to copy
 from a designated place, then offering equivalent access to copy the
 source code from the same place satisfies the requirement to
 distribute the source code, even though third parties are not
 compelled to copy the source along with the object code.
  5. A program that contains no derivative of any portion of the
 Library, but is designed to work with the Library by being compiled or
 linked with it, is called a "work that uses the Library".  Such a
 work, in isolation, is not a derivative work of the Library, and
 therefore falls outside the scope of this License.
  However, linking a "work that uses the Library" with the Library
 creates an executable that is a derivative of the Library (because it
 contains portions of the Library), rather than a "work that uses the
 library".  The executable is therefore covered by this License.
 Section 6 states terms for distribution of such executables.
  When a "work that uses the Library" uses material from a header file
 that is part of the Library, the object code for the work may be a
 derivative work of the Library even though the source code is not.
 Whether this is true is especially significant if the work can be
 linked without the Library, or if the work is itself a library.  The
 threshold for this to be true is not precisely defined by law.
  If such an object file uses only numerical parameters, data
 structure layouts and accessors, and small macros and small inline
 functions (ten lines or less in length), then the use of the object
 file is unrestricted, regardless of whether it is legally a derivative
 work.  (Executables containing this object code plus portions of the
 Library will still fall under Section 6.)
  Otherwise, if the work is a derivative of the Library, you may
 distribute the object code for the work under the terms of Section 6.
 Any executables containing that work also fall under Section 6,
 whether or not they are linked directly with the Library itself.
  6. As an exception to the Sections above, you may also combine or
 link a "work that uses the Library" with the Library to produce a
 work containing portions of the Library, and distribute that work
 under terms of your choice, provided that the terms permit
 modification of the work for the customer's own use and reverse
 engineering for debugging such modifications.
  You must give prominent notice with each copy of the work that the
 Library is used in it and that the Library and its use are covered by
 this License.  You must supply a copy of this License.  If the work
 during execution displays copyright notices, you must include the
 copyright notice for the Library among them, as well as a reference
 directing the user to the copy of this License.  Also, you must do one
 of these things:
    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)
    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.
    c) Accompany the work with a written offer, valid for at least
    three years, to give the same user the materials specified in
    Subsection 6a, above, for a charge no more than the cost of
    performing this distribution.
    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.
    e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.
  For an executable, the required form of the "work that uses the
 Library" must include any data and utility programs needed for
 reproducing the executable from it.  However, as a special exception,
 the materials to be distributed need not include anything that is
 normally distributed (in either source or binary form) with the major
 components (compiler, kernel, and so on) of the operating system on
 which the executable runs, unless that component itself accompanies
 the executable.
  It may happen that this requirement contradicts the license
 restrictions of other proprietary libraries that do not normally
 accompany the operating system.  Such a contradiction means you cannot
 use both them and the Library together in an executable that you
 distribute.
  7. You may place library facilities that are a work based on the
 Library side-by-side in a single library together with other library
 facilities not covered by this License, and distribute such a combined
 library, provided that the separate distribution of the work based on
 the Library and of the other library facilities is otherwise
 permitted, and provided that you do these two things:
    a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.
    b) Give prominent notice with the combined library of the fact
    that part of it is a work based on the Library, and explaining
    where to find the accompanying uncombined form of the same work.
  8. You may not copy, modify, sublicense, link with, or distribute
 the Library except as expressly provided under this License.  Any
 attempt otherwise to copy, modify, sublicense, link with, or
 distribute the Library is void, and will automatically terminate your
 rights under this License.  However, parties who have received copies,
 or rights, from you under this License will not have their licenses
 terminated so long as such parties remain in full compliance.
  9. You are not required to accept this License, since you have not
 signed it.  However, nothing else grants you permission to modify or
 distribute the Library or its derivative works.  These actions are
 prohibited by law if you do not accept this License.  Therefore, by
 modifying or distributing the Library (or any work based on the
 Library), you indicate your acceptance of this License to do so, and
 all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.
  10. Each time you redistribute the Library (or any work based on the
 Library), the recipient automatically receives a license from the
 original licensor to copy, distribute, link with or modify the Library
 subject to these terms and conditions.  You may not impose any further
 restrictions on the recipients' exercise of the rights granted herein.
 You are not responsible for enforcing compliance by third parties with
 this License.
  11. If, as a consequence of a court judgment or allegation of patent
 infringement or for any other reason (not limited to patent issues),
 conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot
 distribute so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you
 may not distribute the Library at all.  For example, if a patent
 license would not permit royalty-free redistribution of the Library by
 all those who receive copies directly or indirectly through you, then
 the only way you could satisfy both it and this License would be to
 refrain entirely from distribution of the Library.
 If any portion of this section is held invalid or unenforceable under
 any particular circumstance, the balance of the section is intended to
 apply, and the section as a whole is intended to apply in other
 circumstances.
 It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system which is
 implemented by public license practices.  Many people have made
 generous contributions to the wide range of software distributed
 through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing
 to distribute software through any other system and a licensee cannot
 impose that choice.
 This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.
  12. If the distribution and/or use of the Library is restricted in
 certain countries either by patents or by copyrighted interfaces, the
 original copyright holder who places the Library under this License
 may add an explicit geographical distribution limitation excluding those
 countries, so that distribution is permitted only in or among
 countries not thus excluded.  In such case, this License incorporates
 the limitation as if written in the body of this License.
  13. The Free Software Foundation may publish revised and/or new
 versions of the Lesser General Public License from time to time.
 Such new versions will be similar in spirit to the present version,
 but may differ in detail to address new problems or concerns.
 Each version is given a distinguishing version number.  If the Library
 specifies a version number of this License which applies to it and
 "any later version", you have the option of following the terms and
 conditions either of that version or of any later version published by
 the Free Software Foundation.  If the Library does not specify a
 license version number, you may choose any version ever published by
 the Free Software Foundation.
  14. If you wish to incorporate parts of the Library into other free
 programs whose distribution conditions are incompatible with these,
 write to the author to ask for permission.  For software which is
 copyrighted by the Free Software Foundation, write to the Free
 Software Foundation; we sometimes make exceptions for this.  Our
 decision will be guided by the two goals of preserving the free status
 of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.
                            NO WARRANTY
  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
 DAMAGES.
                     END OF TERMS AND CONDITIONS
           How to Apply These Terms to Your New Libraries
  If you develop a new library, and you want it to be of the greatest
 possible use to the public, we recommend making it free software that
 everyone can redistribute and change.  You can do so by permitting
 redistribution under these terms (or, alternatively, under the terms
 of the ordinary General Public License).
  To apply these terms, attach the following notices to the library.
 It is safest to attach them to the start of each source file to most
 effectively convey the exclusion of warranty; and each file should
 have at least the "copyright" line and a pointer to where the full
 notice is found.
    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 2.1 of the License, or (at your option) any later version.
    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    Lesser General Public License for more details.
    You should have received a copy of the GNU Lesser General Public
    License along with this library; if not, write to the Free Software
    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
 Also add information on how to contact you by electronic and paper mail.
 You should also get your employer (if you work as a programmer) or
 your school, if any, to sign a "copyright disclaimer" for the library,

 GNU LIBRARY GENERAL PUBLIC LICENSE
 Version 2, June 1991 Copyright (C) 1991 Free Software Foundation, Inc.
 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
 Everyone is permitted to copy and distribute verbatim copies of this license
 document, but changing it is not allowed.
 [This is the first released version of the library GPL. It is numbered 2 because
 it goes with version 2 of the ordinary GPL.]
 Preamble
 The licenses for most software are designed to take away your freedom to share
 and change it. By contrast, the GNU General Public Licenses are intended to
 guarantee your freedom to share and change free software--to make sure the
 software is free for all its users.
 This license, the Library General Public License, applies to some specially
 designated Free Software Foundation software, and to any other libraries whose
 authors decide to use it. You can use it for your libraries, too.
 When we speak of free software, we are referring to freedom, not price. Our
 General Public Licenses are designed to make sure that you have the freedom
 to distribute copies of free software (and charge for this service if you
 wish), that you receive source code or can get it if you want it, that you
 can change the software or use pieces of it in new free programs; and that
 you know you can do these things.
 To protect your rights, we need to make restrictions that forbid anyone to
 deny you these rights or to ask you to surrender the rights. These restrictions
 translate to certain responsibilities for you if you distribute copies of
 the library, or if you modify it.
 For example, if you distribute copies of the library, whether gratis or for
 a fee, you must give the recipients all the rights that we gave you. You must
 make sure that they, too, receive or can get the source code. If you link
 a program with the library, you must provide complete object files to the
 recipients so that they can relink them with the library, after making changes
 to the library and recompiling it. And you must show them these terms so they
 know their rights.
 Our method of protecting your rights has two steps: (1) copyright the library,
 and (2) offer you this license which gives you legal permission to copy, distribute
 and/or modify the library.
 Also, for each distributor's protection, we want to make certain that everyone
 understands that there is no warranty for this free library. If the library
 is modified by someone else and passed on, we want its recipients to know
 that what they have is not the original version, so that any problems introduced
 by others will not reflect on the original authors' reputations.
 Finally, any free program is threatened constantly by software patents. We
 wish to avoid the danger that companies distributing free software will individually
 obtain patent licenses, thus in effect transforming the program into proprietary
 software. To prevent this, we have made it clear that any patent must be licensed
 for everyone's free use or not licensed at all.
 Most GNU software, including some libraries, is covered by the ordinary GNU
 General Public License, which was designed for utility programs. This license,
 the GNU Library General Public License, applies to certain designated libraries.
 This license is quite different from the ordinary one; be sure to read it
 in full, and don't assume that anything in it is the same as in the ordinary
 license.
 The reason we have a separate public license for some libraries is that they
 blur the distinction we usually make between modifying or adding to a program
 and simply using it. Linking a program with a library, without changing the
 library, is in some sense simply using the library, and is analogous to running
 a utility program or application program. However, in a textual and legal
 sense, the linked executable is a combined work, a derivative of the original
 library, and the ordinary General Public License treats it as such.
 Because of this blurred distinction, using the ordinary General Public License
 for libraries did not effectively promote software sharing, because most developers
 did not use the libraries. We concluded that weaker conditions might promote
 sharing better.
 However, unrestricted linking of non-free programs would deprive the users
 of those programs of all benefit from the free status of the libraries themselves.
 This Library General Public License is intended to permit developers of non-free
 programs to use free libraries, while preserving your freedom as a user of
 such programs to change the free libraries that are incorporated in them.
 (We have not seen how to achieve this as regards changes in header files,
 but we have achieved it as regards changes in the actual functions of the
 Library.) The hope is that this will lead to faster development of free libraries.
 The precise terms and conditions for copying, distribution and modification
 follow. Pay close attention to the difference between a "work based on the
 library" and a "work that uses the library". The former contains code derived
 from the library, while the latter only works together with the library.
 Note that it is possible for a library to be covered by the ordinary General
 Public License rather than by this special one.
 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 0. This License Agreement applies to any software library which contains a
 notice placed by the copyright holder or other authorized party saying it
 may be distributed under the terms of this Library General Public License
 (also called "this License"). Each licensee is addressed as "you".
 A "library" means a collection of software functions and/or data prepared
 so as to be conveniently linked with application programs (which use some
 of those functions and data) to form executables.
 The "Library", below, refers to any such software library or work which has
 been distributed under these terms. A "work based on the Library" means either
 the Library or any derivative work under copyright law: that is to say, a
 work containing the Library or a portion of it, either verbatim or with modifications
 and/or translated straightforwardly into another language. (Hereinafter, translation
 is included without limitation in the term "modification".)
 "Source code" for a work means the preferred form of the work for making modifications
 to it. For a library, complete source code means all the source code for all
 modules it contains, plus any associated interface definition files, plus
 the scripts used to control compilation and installation of the library.
 Activities other than copying, distribution and modification are not covered
 by this License; they are outside its scope. The act of running a program
 using the Library is not restricted, and output from such a program is covered
 only if its contents constitute a work based on the Library (independent of
 the use of the Library in a tool for writing it). Whether that is true depends
 on what the Library does and what the program that uses the Library does.
 1. You may copy and distribute verbatim copies of the Library's complete source
 code as you receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice and disclaimer
 of warranty; keep intact all the notices that refer to this License and to
 the absence of any warranty; and distribute a copy of this License along with
 the Library.
 You may charge a fee for the physical act of transferring a copy, and you
 may at your option offer warranty protection in exchange for a fee.
 2. You may modify your copy or copies of the Library or any portion of it,
 thus forming a work based on the Library, and copy and distribute such modifications
 or work under the terms of Section 1 above, provided that you also meet all
 of these conditions:
      a) The modified work must itself be a software library.
 b) You must cause the files modified to carry prominent notices stating that
 you changed the files and the date of any change.
 c) You must cause the whole of the work to be licensed at no charge to all
 third parties under the terms of this License.
 d) If a facility in the modified Library refers to a function or a table of
 data to be supplied by an application program that uses the facility, other
 than as an argument passed when the facility is invoked, then you must make
 a good faith effort to ensure that, in the event an application does not supply
 such function or table, the facility still operates, and performs whatever
 part of its purpose remains meaningful.
 (For example, a function in a library to compute square roots has a purpose
 that is entirely well-defined independent of the application. Therefore, Subsection
 2d requires that any application-supplied function or table used by this function
 must be optional: if the application does not supply it, the square root function
 must still compute square roots.)
 These requirements apply to the modified work as a whole. If identifiable
 sections of that work are not derived from the Library, and can be reasonably
 considered independent and separate works in themselves, then this License,
 and its terms, do not apply to those sections when you distribute them as
 separate works. But when you distribute the same sections as part of a whole
 which is a work based on the Library, the distribution of the whole must be
 on the terms of this License, whose permissions for other licensees extend
 to the entire whole, and thus to each and every part regardless of who wrote
 it.
 Thus, it is not the intent of this section to claim rights or contest your
 rights to work written entirely by you; rather, the intent is to exercise
 the right to control the distribution of derivative or collective works based
 on the Library.
 In addition, mere aggregation of another work not based on the Library with
 the Library (or with a work based on the Library) on a volume of a storage
 or distribution medium does not bring the other work under the scope of this
 License.
 3. You may opt to apply the terms of the ordinary GNU General Public License
 instead of this License to a given copy of the Library. To do this, you must
 alter all the notices that refer to this License, so that they refer to the
 ordinary GNU General Public License, version 2, instead of to this License.
 (If a newer version than version 2 of the ordinary GNU General Public License
 has appeared, then you can specify that version instead if you wish.) Do not
 make any other change in these notices.
 Once this change is made in a given copy, it is irreversible for that copy,
 so the ordinary GNU General Public License applies to all subsequent copies
 and derivative works made from that copy.
 This option is useful when you wish to copy part of the code of the Library
 into a program that is not a library.
 4. You may copy and distribute the Library (or a portion or derivative of
 it, under Section 2) in object code or executable form under the terms of
 Sections 1 and 2 above provided that you accompany it with the complete corresponding
 machine-readable source code, which must be distributed under the terms of
 Sections 1 and 2 above on a medium customarily used for software interchange.
 If distribution of object code is made by offering access to copy from a designated
 place, then offering equivalent access to copy the source code from the same
 place satisfies the requirement to distribute the source code, even though
 third parties are not compelled to copy the source along with the object code.
 5. A program that contains no derivative of any portion of the Library, but
 is designed to work with the Library by being compiled or linked with it,
 is called a "work that uses the Library". Such a work, in isolation, is not
 a derivative work of the Library, and therefore falls outside the scope of
 this License.
 However, linking a "work that uses the Library" with the Library creates an
 executable that is a derivative of the Library (because it contains portions
 of the Library), rather than a "work that uses the library". The executable
 is therefore covered by this License. Section 6 states terms for distribution
 of such executables.
 When a "work that uses the Library" uses material from a header file that
 is part of the Library, the object code for the work may be a derivative work
 of the Library even though the source code is not. Whether this is true is
 especially significant if the work can be linked without the Library, or if
 the work is itself a library. The threshold for this to be true is not precisely
 defined by law.
 If such an object file uses only numerical parameters, data structure layouts
 and accessors, and small macros and small inline functions (ten lines or less
 in length), then the use of the object file is unrestricted, regardless of
 whether it is legally a derivative work. (Executables containing this object
 code plus portions of the Library will still fall under Section 6.)
 Otherwise, if the work is a derivative of the Library, you may distribute
 the object code for the work under the terms of Section 6. Any executables
 containing that work also fall under Section 6, whether or not they are linked
 directly with the Library itself.
 6. As an exception to the Sections above, you may also compile or link a "work
 that uses the Library" with the Library to produce a work containing portions
 of the Library, and distribute that work under terms of your choice, provided
 that the terms permit modification of the work for the customer's own use
 and reverse engineering for debugging such modifications.
 You must give prominent notice with each copy of the work that the Library
 is used in it and that the Library and its use are covered by this License.
 You must supply a copy of this License. If the work during execution displays
 copyright notices, you must include the copyright notice for the Library among
 them, as well as a reference directing the user to the copy of this License.
 Also, you must do one of these things:
 a) Accompany the work with the complete corresponding machine-readable source
 code for the Library including whatever changes were used in the work (which
 must be distributed under Sections 1 and 2 above); and, if the work is an
 executable linked with the Library, with the complete machine-readable "work
 that uses the Library", as object code and/or source code, so that the user
 can modify the Library and then relink to produce a modified executable containing
 the modified Library. (It is understood that the user who changes the contents
 of definitions files in the Library will not necessarily be able to recompile
 the application to use the modified definitions.)
 b) Accompany the work with a written offer, valid for at least three years,
 to give the same user the materials specified in Subsection 6a, above, for
 a charge no more than the cost of performing this distribution.
 c) If distribution of the work is made by offering access to copy from a designated
 place, offer equivalent access to copy the above specified materials from
 the same place.
 d) Verify that the user has already received a copy of these materials or
 that you have already sent this user a copy.
 For an executable, the required form of the "work that uses the Library" must
 include any data and utility programs needed for reproducing the executable
 from it. However, as a special exception, the source code distributed need
 not include anything that is normally distributed (in either source or binary
 form) with the major components (compiler, kernel, and so on) of the operating
 system on which the executable runs, unless that component itself accompanies
 the executable.
 It may happen that this requirement contradicts the license restrictions of
 other proprietary libraries that do not normally accompany the operating system.
 Such a contradiction means you cannot use both them and the Library together
 in an executable that you distribute.
 7. You may place library facilities that are a work based on the Library side-by-side
 in a single library together with other library facilities not covered by
 this License, and distribute such a combined library, provided that the separate
 distribution of the work based on the Library and of the other library facilities
 is otherwise permitted, and provided that you do these two things:
 a) Accompany the combined library with a copy of the same work based on the
 Library, uncombined with any other library facilities. This must be distributed
 under the terms of the Sections above.
 b) Give prominent notice with the combined library of the fact that part of
 it is a work based on the Library, and explaining where to find the accompanying
 uncombined form of the same work.
 8. You may not copy, modify, sublicense, link with, or distribute the Library
 except as expressly provided under this License. Any attempt otherwise to
 copy, modify, sublicense, link with, or distribute the Library is void, and
 will automatically terminate your rights under this License. However, parties
 who have received copies, or rights, from you under this License will not
 have their licenses terminated so long as such parties remain in full compliance.
 9. You are not required to accept this License, since you have not signed
 it. However, nothing else grants you permission to modify or distribute the
 Library or its derivative works. These actions are prohibited by law if you
 do not accept this License. Therefore, by modifying or distributing the Library
 (or any work based on the Library), you indicate your acceptance of this License
 to do so, and all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.
 10. Each time you redistribute the Library (or any work based on the Library),
 the recipient automatically receives a license from the original licensor
 to copy, distribute, link with or modify the Library subject to these terms
 and conditions. You may not impose any further restrictions on the recipients'
 exercise of the rights granted herein. You are not responsible for enforcing
 compliance by third parties to this License.
 11. If, as a consequence of a court judgment or allegation of patent infringement
 or for any other reason (not limited to patent issues), conditions are imposed
 on you (whether by court order, agreement or otherwise) that contradict the
 conditions of this License, they do not excuse you from the conditions of
 this License. If you cannot distribute so as to satisfy simultaneously your
 obligations under this License and any other pertinent obligations, then as
 a consequence you may not distribute the Library at all. For example, if a
 patent license would not permit royalty-free redistribution of the Library
 by all those who receive copies directly or indirectly through you, then the
 only way you could satisfy both it and this License would be to refrain entirely
 from distribution of the Library.
 If any portion of this section is held invalid or unenforceable under any
 particular circumstance, the balance of the section is intended to apply,
 and the section as a whole is intended to apply in other circumstances.
 It is not the purpose of this section to induce you to infringe any patents
 or other property right claims or to contest validity of any such claims;
 this section has the sole purpose of protecting the integrity of the free
 software distribution system which is implemented by public license practices.
 Many people have made generous contributions to the wide range of software
 distributed through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing to
 distribute software through any other system and a licensee cannot impose
 that choice.
 This section is intended to make thoroughly clear what is believed to be a
 consequence of the rest of this License.
 12. If the distribution and/or use of the Library is restricted in certain
 countries either by patents or by copyrighted interfaces, the original copyright
 holder who places the Library under this License may add an explicit geographical
 distribution limitation excluding those countries, so that distribution is
 permitted only in or among countries not thus excluded. In such case, this
 License incorporates the limitation as if written in the body of this License.
 13. The Free Software Foundation may publish revised and/or new versions of
 the Library General Public License from time to time. Such new versions will
 be similar in spirit to the present version, but may differ in detail to address
 new problems or concerns.
 Each version is given a distinguishing version number. If the Library specifies
 a version number of this License which applies to it and "any later version",
 you have the option of following the terms and conditions either of that version
 or of any later version published by the Free Software Foundation. If the
 Library does not specify a license version number, you may choose any version
 ever published by the Free Software Foundation.
 14. If you wish to incorporate parts of the Library into other free programs
 whose distribution conditions are incompatible with these, write to the author
 to ask for permission. For software which is copyrighted by the Free Software
 Foundation, write to the Free Software Foundation; we sometimes make exceptions
 for this. Our decision will be guided by the two goals of preserving the free
 status of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.
   NO WARRANTY
 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
 THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
 "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
 BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
 FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
 OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
 THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
 OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
 OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 END OF TERMS AND CONDITIONS
 How to Apply These Terms to Your New Libraries
 If you develop a new library, and you want it to be of the greatest possible
 use to the public, we recommend making it free software that everyone can
 redistribute and change. You can do so by permitting redistribution under
 these terms (or, alternatively, under the terms of the ordinary General Public
 License).
 To apply these terms, attach the following notices to the library. It is safest
 to attach them to the start of each source file to most effectively convey
 the exclusion of warranty; and each file should have at least the "copyright"
 line and a pointer to where the full notice is found.
 one line to give the library's name and an idea of what it does.
 Copyright (C) year name of author
 This library is free software; you can redistribute it and/or modify it under
 the terms of the GNU Library General Public License as published by the Free
 Software Foundation; either version 2 of the License, or (at your option)
 any later version.
 This library is distributed in the hope that it will be useful, but WITHOUT
 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
 FOR A PARTICULAR PURPOSE. See the GNU Library General Public License for more
 details.
 You should have received a copy of the GNU Library General Public License
 along with this library; if not, write to the Free Software Foundation, Inc.,
 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.
 Also add information on how to contact you by electronic and paper mail.
 You should also get your employer (if you work as a programmer) or your school,
 if any, to sign a "copyright disclaimer" for the library, if necessary. Here
 is a sample; alter the names:

 GNU LESSER GENERAL PUBLIC LICENSE
 Version 2.1, February 1999
 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies of this license
 document, but changing it is not allowed.
 [This is the first released version of the Lesser GPL. It also counts as the
 successor of the GNU Library Public License, version 2, hence the version
 number 2.1.]
 Preamble
 The licenses for most software are designed to take away your freedom to share
 and change it. By contrast, the GNU General Public Licenses are intended to
 guarantee your freedom to share and change free software--to make sure the
 software is free for all its users.
 This license, the Lesser General Public License, applies to some specially
 designated software packages--typically libraries--of the Free Software Foundation
 and other authors who decide to use it. You can use it too, but we suggest
 you first think carefully about whether this license or the ordinary General
 Public License is the better strategy to use in any particular case, based
 on the explanations below.
 When we speak of free software, we are referring to freedom of use, not price.
 Our General Public Licenses are designed to make sure that you have the freedom
 to distribute copies of free software (and charge for this service if you
 wish); that you receive source code or can get it if you want it; that you
 can change the software and use pieces of it in new free programs; and that
 you are informed that you can do these things.
 To protect your rights, we need to make restrictions that forbid distributors
 to deny you these rights or to ask you to surrender these rights. These restrictions
 translate to certain responsibilities for you if you distribute copies of
 the library or if you modify it.
 For example, if you distribute copies of the library, whether gratis or for
 a fee, you must give the recipients all the rights that we gave you. You must
 make sure that they, too, receive or can get the source code. If you link
 other code with the library, you must provide complete object files to the
 recipients, so that they can relink them with the library after making changes
 to the library and recompiling it. And you must show them these terms so they
 know their rights.
 We protect your rights with a two-step method: (1) we copyright the library,
 and (2) we offer you this license, which gives you legal permission to copy,
 distribute and/or modify the library.
 To protect each distributor, we want to make it very clear that there is no
 warranty for the free library. Also, if the library is modified by someone
 else and passed on, the recipients should know that what they have is not
 the original version, so that the original author's reputation will not be
 affected by problems that might be introduced by others.
 Finally, software patents pose a constant threat to the existence of any free
 program. We wish to make sure that a company cannot effectively restrict the
 users of a free program by obtaining a restrictive license from a patent holder.
 Therefore, we insist that any patent license obtained for a version of the
 library must be consistent with the full freedom of use specified in this
 license.
 Most GNU software, including some libraries, is covered by the ordinary GNU
 General Public License. This license, the GNU Lesser General Public License,
 applies to certain designated libraries, and is quite different from the ordinary
 General Public License. We use this license for certain libraries in order
 to permit linking those libraries into non-free programs.
 When a program is linked with a library, whether statically or using a shared
 library, the combination of the two is legally speaking a combined work, a
 derivative of the original library. The ordinary General Public License therefore
 permits such linking only if the entire combination fits its criteria of freedom.
 The Lesser General Public License permits more lax criteria for linking other
 code with the library.
 We call this license the "Lesser" General Public License because it does Less
 to protect the user's freedom than the ordinary General Public License. It
 also provides other free software developers Less of an advantage over competing
 non-free programs. These disadvantages are the reason we use the ordinary
 General Public License for many libraries. However, the Lesser license provides
 advantages in certain special circumstances.
 For example, on rare occasions, there may be a special need to encourage the
 widest possible use of a certain library, so that it becomes a de-facto standard.
 To achieve this, non-free programs must be allowed to use the library. A more
 frequent case is that a free library does the same job as widely used non-free
 libraries. In this case, there is little to gain by limiting the free library
 to free software only, so we use the Lesser General Public License.
 In other cases, permission to use a particular library in non-free programs
 enables a greater number of people to use a large body of free software. For
 example, permission to use the GNU C Library in non-free programs enables
 many more people to use the whole GNU operating system, as well as its variant,
 the GNU/Linux operating system.
 Although the Lesser General Public License is Less protective of the users'
 freedom, it does ensure that the user of a program that is linked with the
 Library has the freedom and the wherewithal to run that program using a modified
 version of the Library.
 The precise terms and conditions for copying, distribution and modification
 follow. Pay close attention to the difference between a "work based on the
 library" and a "work that uses the library". The former contains code derived
 from the library, whereas the latter must be combined with the library in
 order to run.
 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 0. This License Agreement applies to any software library or other program
 which contains a notice placed by the copyright holder or other authorized
 party saying it may be distributed under the terms of this Lesser General
 Public License (also called "this License"). Each licensee is addressed as
 "you".
 A "library" means a collection of software functions and/or data prepared
 so as to be conveniently linked with application programs (which use some
 of those functions and data) to form executables.
 The "Library", below, refers to any such software library or work which has
 been distributed under these terms. A "work based on the Library" means either
 the Library or any derivative work under copyright law: that is to say, a
 work containing the Library or a portion of it, either verbatim or with modifications
 and/or translated straightforwardly into another language. (Hereinafter, translation
 is included without limitation in the term "modification".)
 "Source code" for a work means the preferred form of the work for making modifications
 to it. For a library, complete source code means all the source code for all
 modules it contains, plus any associated interface definition files, plus
 the scripts used to control compilation and installation of the library.
 Activities other than copying, distribution and modification are not covered
 by this License; they are outside its scope. The act of running a program
 using the Library is not restricted, and output from such a program is covered
 only if its contents constitute a work based on the Library (independent of
 the use of the Library in a tool for writing it). Whether that is true depends
 on what the Library does and what the program that uses the Library does.
 1. You may copy and distribute verbatim copies of the Library's complete source
 code as you receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice and disclaimer
 of warranty; keep intact all the notices that refer to this License and to
 the absence of any warranty; and distribute a copy of this License along with
 the Library.
 You may charge a fee for the physical act of transferring a copy, and you
 may at your option offer warranty protection in exchange for a fee.
 2. You may modify your copy or copies of the Library or any portion of it,
 thus forming a work based on the Library, and copy and distribute such modifications
 or work under the terms of Section 1 above, provided that you also meet all
 of these conditions:
      a) The modified work must itself be a software library.
 b) You must cause the files modified to carry prominent notices stating that
 you changed the files and the date of any change.
 c) You must cause the whole of the work to be licensed at no charge to all
 third parties under the terms of this License.
 d) If a facility in the modified Library refers to a function or a table of
 data to be supplied by an application program that uses the facility, other
 than as an argument passed when the facility is invoked, then you must make
 a good faith effort to ensure that, in the event an application does not supply
 such function or table, the facility still operates, and performs whatever
 part of its purpose remains meaningful.
 (For example, a function in a library to compute square roots has a purpose
 that is entirely well-defined independent of the application. Therefore, Subsection
 2d requires that any application-supplied function or table used by this function
 must be optional: if the application does not supply it, the square root function
 must still compute square roots.)
 These requirements apply to the modified work as a whole. If identifiable
 sections of that work are not derived from the Library, and can be reasonably
 considered independent and separate works in themselves, then this License,
 and its terms, do not apply to those sections when you distribute them as
 separate works. But when you distribute the same sections as part of a whole
 which is a work based on the Library, the distribution of the whole must be
 on the terms of this License, whose permissions for other licensees extend
 to the entire whole, and thus to each and every part regardless of who wrote
 it.
 Thus, it is not the intent of this section to claim rights or contest your
 rights to work written entirely by you; rather, the intent is to exercise
 the right to control the distribution of derivative or collective works based
 on the Library.
 In addition, mere aggregation of another work not based on the Library with
 the Library (or with a work based on the Library) on a volume of a storage
 or distribution medium does not bring the other work under the scope of this
 License.
 3. You may opt to apply the terms of the ordinary GNU General Public License
 instead of this License to a given copy of the Library. To do this, you must
 alter all the notices that refer to this License, so that they refer to the
 ordinary GNU General Public License, version 2, instead of to this License.
 (If a newer version than version 2 of the ordinary GNU General Public License
 has appeared, then you can specify that version instead if you wish.) Do not
 make any other change in these notices.
 Once this change is made in a given copy, it is irreversible for that copy,
 so the ordinary GNU General Public License applies to all subsequent copies
 and derivative works made from that copy.
 This option is useful when you wish to copy part of the code of the Library
 into a program that is not a library.
 4. You may copy and distribute the Library (or a portion or derivative of
 it, under Section 2) in object code or executable form under the terms of
 Sections 1 and 2 above provided that you accompany it with the complete corresponding
 machine-readable source code, which must be distributed under the terms of
 Sections 1 and 2 above on a medium customarily used for software interchange.
 If distribution of object code is made by offering access to copy from a designated
 place, then offering equivalent access to copy the source code from the same
 place satisfies the requirement to distribute the source code, even though
 third parties are not compelled to copy the source along with the object code.
 5. A program that contains no derivative of any portion of the Library, but
 is designed to work with the Library by being compiled or linked with it,
 is called a "work that uses the Library". Such a work, in isolation, is not
 a derivative work of the Library, and therefore falls outside the scope of
 this License.
 However, linking a "work that uses the Library" with the Library creates an
 executable that is a derivative of the Library (because it contains portions
 of the Library), rather than a "work that uses the library". The executable
 is therefore covered by this License. Section 6 states terms for distribution
 of such executables.
 When a "work that uses the Library" uses material from a header file that
 is part of the Library, the object code for the work may be a derivative work
 of the Library even though the source code is not. Whether this is true is
 especially significant if the work can be linked without the Library, or if
 the work is itself a library. The threshold for this to be true is not precisely
 defined by law.
 If such an object file uses only numerical parameters, data structure layouts
 and accessors, and small macros and small inline functions (ten lines or less
 in length), then the use of the object file is unrestricted, regardless of
 whether it is legally a derivative work. (Executables containing this object
 code plus portions of the Library will still fall under Section 6.)
 Otherwise, if the work is a derivative of the Library, you may distribute
 the object code for the work under the terms of Section 6. Any executables
 containing that work also fall under Section 6, whether or not they are linked
 directly with the Library itself.
 6. As an exception to the Sections above, you may also combine or link a "work
 that uses the Library" with the Library to produce a work containing portions
 of the Library, and distribute that work under terms of your choice, provided
 that the terms permit modification of the work for the customer's own use
 and reverse engineering for debugging such modifications.
 You must give prominent notice with each copy of the work that the Library
 is used in it and that the Library and its use are covered by this License.
 You must supply a copy of this License. If the work during execution displays
 copyright notices, you must include the copyright notice for the Library among
 them, as well as a reference directing the user to the copy of this License.
 Also, you must do one of these things:
 a) Accompany the work with the complete corresponding machine-readable source
 code for the Library including whatever changes were used in the work (which
 must be distributed under Sections 1 and 2 above); and, if the work is an
 executable linked with the Library, with the complete machine-readable "work
 that uses the Library", as object code and/or source code, so that the user
 can modify the Library and then relink to produce a modified executable containing
 the modified Library. (It is understood that the user who changes the contents
 of definitions files in the Library will not necessarily be able to recompile
 the application to use the modified definitions.)
 b) Use a suitable shared library mechanism for linking with the Library. A
 suitable mechanism is one that (1) uses at run time a copy of the library
 already present on the user's computer system, rather than copying library
 functions into the executable, and (2) will operate properly with a modified
 version of the library, if the user installs one, as long as the modified
 version is interface-compatible with the version that the work was made with.
 c) Accompany the work with a written offer, valid for at least three years,
 to give the same user the materials specified in Subsection 6a, above, for
 a charge no more than the cost of performing this distribution.
 d) If distribution of the work is made by offering access to copy from a designated
 place, offer equivalent access to copy the above specified materials from
 the same place.
 e) Verify that the user has already received a copy of these materials or
 that you have already sent this user a copy.
 For an executable, the required form of the "work that uses the Library" must
 include any data and utility programs needed for reproducing the executable
 from it. However, as a special exception, the materials to be distributed
 need not include anything that is normally distributed (in either source or
 binary form) with the major components (compiler, kernel, and so on) of the
 operating system on which the executable runs, unless that component itself
 accompanies the executable.
 It may happen that this requirement contradicts the license restrictions of
 other proprietary libraries that do not normally accompany the operating system.
 Such a contradiction means you cannot use both them and the Library together
 in an executable that you distribute.
 7. You may place library facilities that are a work based on the Library side-by-side
 in a single library together with other library facilities not covered by
 this License, and distribute such a combined library, provided that the separate
 distribution of the work based on the Library and of the other library facilities
 is otherwise permitted, and provided that you do these two things:
 a) Accompany the combined library with a copy of the same work based on the
 Library, uncombined with any other library facilities. This must be distributed
 under the terms of the Sections above.
 b) Give prominent notice with the combined library of the fact that part of
 it is a work based on the Library, and explaining where to find the accompanying
 uncombined form of the same work.
 8. You may not copy, modify, sublicense, link with, or distribute the Library
 except as expressly provided under this License. Any attempt otherwise to
 copy, modify, sublicense, link with, or distribute the Library is void, and
 will automatically terminate your rights under this License. However, parties
 who have received copies, or rights, from you under this License will not
 have their licenses terminated so long as such parties remain in full compliance.
 9. You are not required to accept this License, since you have not signed
 it. However, nothing else grants you permission to modify or distribute the
 Library or its derivative works. These actions are prohibited by law if you
 do not accept this License. Therefore, by modifying or distributing the Library
 (or any work based on the Library), you indicate your acceptance of this License
 to do so, and all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.
 10. Each time you redistribute the Library (or any work based on the Library),
 the recipient automatically receives a license from the original licensor
 to copy, distribute, link with or modify the Library subject to these terms
 and conditions. You may not impose any further restrictions on the recipients'
 exercise of the rights granted herein. You are not responsible for enforcing
 compliance by third parties with this License.
 11. If, as a consequence of a court judgment or allegation of patent infringement
 or for any other reason (not limited to patent issues), conditions are imposed
 on you (whether by court order, agreement or otherwise) that contradict the
 conditions of this License, they do not excuse you from the conditions of
 this License. If you cannot distribute so as to satisfy simultaneously your
 obligations under this License and any other pertinent obligations, then as
 a consequence you may not distribute the Library at all. For example, if a
 patent license would not permit royalty-free redistribution of the Library
 by all those who receive copies directly or indirectly through you, then the
 only way you could satisfy both it and this License would be to refrain entirely
 from distribution of the Library.
 If any portion of this section is held invalid or unenforceable under any
 particular circumstance, the balance of the section is intended to apply,
 and the section as a whole is intended to apply in other circumstances.
 It is not the purpose of this section to induce you to infringe any patents
 or other property right claims or to contest validity of any such claims;
 this section has the sole purpose of protecting the integrity of the free
 software distribution system which is implemented by public license practices.
 Many people have made generous contributions to the wide range of software
 distributed through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing to
 distribute software through any other system and a licensee cannot impose
 that choice.
 This section is intended to make thoroughly clear what is believed to be a
 consequence of the rest of this License.
 12. If the distribution and/or use of the Library is restricted in certain
 countries either by patents or by copyrighted interfaces, the original copyright
 holder who places the Library under this License may add an explicit geographical
 distribution limitation excluding those countries, so that distribution is
 permitted only in or among countries not thus excluded. In such case, this
 License incorporates the limitation as if written in the body of this License.
 13. The Free Software Foundation may publish revised and/or new versions of
 the Lesser General Public License from time to time. Such new versions will
 be similar in spirit to the present version, but may differ in detail to address
 new problems or concerns.
 Each version is given a distinguishing version number. If the Library specifies
 a version number of this License which applies to it and "any later version",
 you have the option of following the terms and conditions either of that version
 or of any later version published by the Free Software Foundation. If the
 Library does not specify a license version number, you may choose any version
 ever published by the Free Software Foundation.
 14. If you wish to incorporate parts of the Library into other free programs
 whose distribution conditions are incompatible with these, write to the author
 to ask for permission. For software which is copyrighted by the Free Software
 Foundation, write to the Free Software Foundation; we sometimes make exceptions
 for this. Our decision will be guided by the two goals of preserving the free
 status of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.
   NO WARRANTY
 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
 THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
 "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
 BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
 FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
 OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
 THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
 OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
 OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 END OF TERMS AND CONDITIONS
 How to Apply These Terms to Your New Libraries
 If you develop a new library, and you want it to be of the greatest possible
 use to the public, we recommend making it free software that everyone can
 redistribute and change. You can do so by permitting redistribution under
 these terms (or, alternatively, under the terms of the ordinary General Public
 License).
 To apply these terms, attach the following notices to the library. It is safest
 to attach them to the start of each source file to most effectively convey
 the exclusion of warranty; and each file should have at least the "copyright"
 line and a pointer to where the full notice is found.
 < one line to give the library's name and an idea of what it does. >
 Copyright (C) < year > < name of author >
 This library is free software; you can redistribute it and/or modify it under
 the terms of the GNU Lesser General Public License as published by the Free
 Software Foundation; either version 2.1 of the License, or (at your option)
 any later version.
 This library is distributed in the hope that it will be useful, but WITHOUT
 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
 FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more
 details.
 You should have received a copy of the GNU Lesser General Public License along
 with this library; if not, write to the Free Software Foundation, Inc., 51
 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information
 on how to contact you by electronic and paper mail.
 You should also get your employer (if you work as a programmer) or your school,
 if any, to sign a "copyright disclaimer" for the library, if necessary. Here
 is a sample; alter the names:
 Yoyodyne, Inc., hereby disclaims all copyright interest in
 the library `Frob' (a library for tweaking knobs) written

 GNU LESSER GENERAL PUBLIC LICENSE
 Version 2.1, February 1999
 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies of this license
 document, but changing it is not allowed.
 [This is the first released version of the Lesser GPL. It also counts as the
 successor of the GNU Library Public License, version 2, hence the version
 number 2.1.]
 Preamble
 The licenses for most software are designed to take away your freedom to share
 and change it. By contrast, the GNU General Public Licenses are intended to
 guarantee your freedom to share and change free software--to make sure the
 software is free for all its users.
 This license, the Lesser General Public License, applies to some specially
 designated software packages--typically libraries--of the Free Software Foundation
 and other authors who decide to use it. You can use it too, but we suggest
 you first think carefully about whether this license or the ordinary General
 Public License is the better strategy to use in any particular case, based
 on the explanations below.
 When we speak of free software, we are referring to freedom of use, not price.
 Our General Public Licenses are designed to make sure that you have the freedom
 to distribute copies of free software (and charge for this service if you
 wish); that you receive source code or can get it if you want it; that you
 can change the software and use pieces of it in new free programs; and that
 you are informed that you can do these things.
 To protect your rights, we need to make restrictions that forbid distributors
 to deny you these rights or to ask you to surrender these rights. These restrictions
 translate to certain responsibilities for you if you distribute copies of
 the library or if you modify it.
 For example, if you distribute copies of the library, whether gratis or for
 a fee, you must give the recipients all the rights that we gave you. You must
 make sure that they, too, receive or can get the source code. If you link
 other code with the library, you must provide complete object files to the
 recipients, so that they can relink them with the library after making changes
 to the library and recompiling it. And you must show them these terms so they
 know their rights.
 We protect your rights with a two-step method: (1) we copyright the library,
 and (2) we offer you this license, which gives you legal permission to copy,
 distribute and/or modify the library.
 To protect each distributor, we want to make it very clear that there is no
 warranty for the free library. Also, if the library is modified by someone
 else and passed on, the recipients should know that what they have is not
 the original version, so that the original author's reputation will not be
 affected by problems that might be introduced by others.
 Finally, software patents pose a constant threat to the existence of any free
 program. We wish to make sure that a company cannot effectively restrict the
 users of a free program by obtaining a restrictive license from a patent holder.
 Therefore, we insist that any patent license obtained for a version of the
 library must be consistent with the full freedom of use specified in this
 license.
 Most GNU software, including some libraries, is covered by the ordinary GNU
 General Public License. This license, the GNU Lesser General Public License,
 applies to certain designated libraries, and is quite different from the ordinary
 General Public License. We use this license for certain libraries in order
 to permit linking those libraries into non-free programs.
 When a program is linked with a library, whether statically or using a shared
 library, the combination of the two is legally speaking a combined work, a
 derivative of the original library. The ordinary General Public License therefore
 permits such linking only if the entire combination fits its criteria of freedom.
 The Lesser General Public License permits more lax criteria for linking other
 code with the library.
 We call this license the "Lesser" General Public License because it does Less
 to protect the user's freedom than the ordinary General Public License. It
 also provides other free software developers Less of an advantage over competing
 non-free programs. These disadvantages are the reason we use the ordinary
 General Public License for many libraries. However, the Lesser license provides
 advantages in certain special circumstances.
 For example, on rare occasions, there may be a special need to encourage the
 widest possible use of a certain library, so that it becomes a de-facto standard.
 To achieve this, non-free programs must be allowed to use the library. A more
 frequent case is that a free library does the same job as widely used non-free
 libraries. In this case, there is little to gain by limiting the free library
 to free software only, so we use the Lesser General Public License.
 In other cases, permission to use a particular library in non-free programs
 enables a greater number of people to use a large body of free software. For
 example, permission to use the GNU C Library in non-free programs enables
 many more people to use the whole GNU operating system, as well as its variant,
 the GNU/Linux operating system.
 Although the Lesser General Public License is Less protective of the users'
 freedom, it does ensure that the user of a program that is linked with the
 Library has the freedom and the wherewithal to run that program using a modified
 version of the Library.
 The precise terms and conditions for copying, distribution and modification
 follow. Pay close attention to the difference between a "work based on the
 library" and a "work that uses the library". The former contains code derived
 from the library, whereas the latter must be combined with the library in
 order to run.
 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 0. This License Agreement applies to any software library or other program
 which contains a notice placed by the copyright holder or other authorized
 party saying it may be distributed under the terms of this Lesser General
 Public License (also called "this License"). Each licensee is addressed as
 "you".
 A "library" means a collection of software functions and/or data prepared
 so as to be conveniently linked with application programs (which use some
 of those functions and data) to form executables.
 The "Library", below, refers to any such software library or work which has
 been distributed under these terms. A "work based on the Library" means either
 the Library or any derivative work under copyright law: that is to say, a
 work containing the Library or a portion of it, either verbatim or with modifications
 and/or translated straightforwardly into another language. (Hereinafter, translation
 is included without limitation in the term "modification".)
 "Source code" for a work means the preferred form of the work for making modifications
 to it. For a library, complete source code means all the source code for all
 modules it contains, plus any associated interface definition files, plus
 the scripts used to control compilation and installation of the library.
 Activities other than copying, distribution and modification are not covered
 by this License; they are outside its scope. The act of running a program
 using the Library is not restricted, and output from such a program is covered
 only if its contents constitute a work based on the Library (independent of
 the use of the Library in a tool for writing it). Whether that is true depends
 on what the Library does and what the program that uses the Library does.
 1. You may copy and distribute verbatim copies of the Library's complete source
 code as you receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice and disclaimer
 of warranty; keep intact all the notices that refer to this License and to
 the absence of any warranty; and distribute a copy of this License along with
 the Library.
 You may charge a fee for the physical act of transferring a copy, and you
 may at your option offer warranty protection in exchange for a fee.
 2. You may modify your copy or copies of the Library or any portion of it,
 thus forming a work based on the Library, and copy and distribute such modifications
 or work under the terms of Section 1 above, provided that you also meet all
 of these conditions:
      a) The modified work must itself be a software library.
 b) You must cause the files modified to carry prominent notices stating that
 you changed the files and the date of any change.
 c) You must cause the whole of the work to be licensed at no charge to all
 third parties under the terms of this License.
 d) If a facility in the modified Library refers to a function or a table of
 data to be supplied by an application program that uses the facility, other
 than as an argument passed when the facility is invoked, then you must make
 a good faith effort to ensure that, in the event an application does not supply
 such function or table, the facility still operates, and performs whatever
 part of its purpose remains meaningful.
 (For example, a function in a library to compute square roots has a purpose
 that is entirely well-defined independent of the application. Therefore, Subsection
 2d requires that any application-supplied function or table used by this function
 must be optional: if the application does not supply it, the square root function
 must still compute square roots.)
 These requirements apply to the modified work as a whole. If identifiable
 sections of that work are not derived from the Library, and can be reasonably
 considered independent and separate works in themselves, then this License,
 and its terms, do not apply to those sections when you distribute them as
 separate works. But when you distribute the same sections as part of a whole
 which is a work based on the Library, the distribution of the whole must be
 on the terms of this License, whose permissions for other licensees extend
 to the entire whole, and thus to each and every part regardless of who wrote
 it.
 Thus, it is not the intent of this section to claim rights or contest your
 rights to work written entirely by you; rather, the intent is to exercise
 the right to control the distribution of derivative or collective works based
 on the Library.
 In addition, mere aggregation of another work not based on the Library with
 the Library (or with a work based on the Library) on a volume of a storage
 or distribution medium does not bring the other work under the scope of this
 License.
 3. You may opt to apply the terms of the ordinary GNU General Public License
 instead of this License to a given copy of the Library. To do this, you must
 alter all the notices that refer to this License, so that they refer to the
 ordinary GNU General Public License, version 2, instead of to this License.
 (If a newer version than version 2 of the ordinary GNU General Public License
 has appeared, then you can specify that version instead if you wish.) Do not
 make any other change in these notices.
 Once this change is made in a given copy, it is irreversible for that copy,
 so the ordinary GNU General Public License applies to all subsequent copies
 and derivative works made from that copy.
 This option is useful when you wish to copy part of the code of the Library
 into a program that is not a library.
 4. You may copy and distribute the Library (or a portion or derivative of
 it, under Section 2) in object code or executable form under the terms of
 Sections 1 and 2 above provided that you accompany it with the complete corresponding
 machine-readable source code, which must be distributed under the terms of
 Sections 1 and 2 above on a medium customarily used for software interchange.
 If distribution of object code is made by offering access to copy from a designated
 place, then offering equivalent access to copy the source code from the same
 place satisfies the requirement to distribute the source code, even though
 third parties are not compelled to copy the source along with the object code.
 5. A program that contains no derivative of any portion of the Library, but
 is designed to work with the Library by being compiled or linked with it,
 is called a "work that uses the Library". Such a work, in isolation, is not
 a derivative work of the Library, and therefore falls outside the scope of
 this License.
 However, linking a "work that uses the Library" with the Library creates an
 executable that is a derivative of the Library (because it contains portions
 of the Library), rather than a "work that uses the library". The executable
 is therefore covered by this License. Section 6 states terms for distribution
 of such executables.
 When a "work that uses the Library" uses material from a header file that
 is part of the Library, the object code for the work may be a derivative work
 of the Library even though the source code is not. Whether this is true is
 especially significant if the work can be linked without the Library, or if
 the work is itself a library. The threshold for this to be true is not precisely
 defined by law.
 If such an object file uses only numerical parameters, data structure layouts
 and accessors, and small macros and small inline functions (ten lines or less
 in length), then the use of the object file is unrestricted, regardless of
 whether it is legally a derivative work. (Executables containing this object
 code plus portions of the Library will still fall under Section 6.)
 Otherwise, if the work is a derivative of the Library, you may distribute
 the object code for the work under the terms of Section 6. Any executables
 containing that work also fall under Section 6, whether or not they are linked
 directly with the Library itself.
 6. As an exception to the Sections above, you may also combine or link a "work
 that uses the Library" with the Library to produce a work containing portions
 of the Library, and distribute that work under terms of your choice, provided
 that the terms permit modification of the work for the customer's own use
 and reverse engineering for debugging such modifications.
 You must give prominent notice with each copy of the work that the Library
 is used in it and that the Library and its use are covered by this License.
 You must supply a copy of this License. If the work during execution displays
 copyright notices, you must include the copyright notice for the Library among
 them, as well as a reference directing the user to the copy of this License.
 Also, you must do one of these things:
 a) Accompany the work with the complete corresponding machine-readable source
 code for the Library including whatever changes were used in the work (which
 must be distributed under Sections 1 and 2 above); and, if the work is an
 executable linked with the Library, with the complete machine-readable "work
 that uses the Library", as object code and/or source code, so that the user
 can modify the Library and then relink to produce a modified executable containing
 the modified Library. (It is understood that the user who changes the contents
 of definitions files in the Library will not necessarily be able to recompile
 the application to use the modified definitions.)
 b) Use a suitable shared library mechanism for linking with the Library. A
 suitable mechanism is one that (1) uses at run time a copy of the library
 already present on the user's computer system, rather than copying library
 functions into the executable, and (2) will operate properly with a modified
 version of the library, if the user installs one, as long as the modified
 version is interface-compatible with the version that the work was made with.
 c) Accompany the work with a written offer, valid for at least three years,
 to give the same user the materials specified in Subsection 6a, above, for
 a charge no more than the cost of performing this distribution.
 d) If distribution of the work is made by offering access to copy from a designated
 place, offer equivalent access to copy the above specified materials from
 the same place.
 e) Verify that the user has already received a copy of these materials or
 that you have already sent this user a copy.
 For an executable, the required form of the "work that uses the Library" must
 include any data and utility programs needed for reproducing the executable
 from it. However, as a special exception, the materials to be distributed
 need not include anything that is normally distributed (in either source or
 binary form) with the major components (compiler, kernel, and so on) of the
 operating system on which the executable runs, unless that component itself
 accompanies the executable.
 It may happen that this requirement contradicts the license restrictions of
 other proprietary libraries that do not normally accompany the operating system.
 Such a contradiction means you cannot use both them and the Library together
 in an executable that you distribute.
 7. You may place library facilities that are a work based on the Library side-by-side
 in a single library together with other library facilities not covered by
 this License, and distribute such a combined library, provided that the separate
 distribution of the work based on the Library and of the other library facilities
 is otherwise permitted, and provided that you do these two things:
 a) Accompany the combined library with a copy of the same work based on the
 Library, uncombined with any other library facilities. This must be distributed
 under the terms of the Sections above.
 b) Give prominent notice with the combined library of the fact that part of
 it is a work based on the Library, and explaining where to find the accompanying
 uncombined form of the same work.
 8. You may not copy, modify, sublicense, link with, or distribute the Library
 except as expressly provided under this License. Any attempt otherwise to
 copy, modify, sublicense, link with, or distribute the Library is void, and
 will automatically terminate your rights under this License. However, parties
 who have received copies, or rights, from you under this License will not
 have their licenses terminated so long as such parties remain in full compliance.
 9. You are not required to accept this License, since you have not signed
 it. However, nothing else grants you permission to modify or distribute the
 Library or its derivative works. These actions are prohibited by law if you
 do not accept this License. Therefore, by modifying or distributing the Library
 (or any work based on the Library), you indicate your acceptance of this License
 to do so, and all its terms and conditions for copying, distributing or modifying
 the Library or works based on it.
 10. Each time you redistribute the Library (or any work based on the Library),
 the recipient automatically receives a license from the original licensor
 to copy, distribute, link with or modify the Library subject to these terms
 and conditions. You may not impose any further restrictions on the recipients'
 exercise of the rights granted herein. You are not responsible for enforcing
 compliance by third parties with this License.
 11. If, as a consequence of a court judgment or allegation of patent infringement
 or for any other reason (not limited to patent issues), conditions are imposed
 on you (whether by court order, agreement or otherwise) that contradict the
 conditions of this License, they do not excuse you from the conditions of
 this License. If you cannot distribute so as to satisfy simultaneously your
 obligations under this License and any other pertinent obligations, then as
 a consequence you may not distribute the Library at all. For example, if a
 patent license would not permit royalty-free redistribution of the Library
 by all those who receive copies directly or indirectly through you, then the
 only way you could satisfy both it and this License would be to refrain entirely
 from distribution of the Library.
 If any portion of this section is held invalid or unenforceable under any
 particular circumstance, the balance of the section is intended to apply,
 and the section as a whole is intended to apply in other circumstances.
 It is not the purpose of this section to induce you to infringe any patents
 or other property right claims or to contest validity of any such claims;
 this section has the sole purpose of protecting the integrity of the free
 software distribution system which is implemented by public license practices.
 Many people have made generous contributions to the wide range of software
 distributed through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing to
 distribute software through any other system and a licensee cannot impose
 that choice.
 This section is intended to make thoroughly clear what is believed to be a
 consequence of the rest of this License.
 12. If the distribution and/or use of the Library is restricted in certain
 countries either by patents or by copyrighted interfaces, the original copyright
 holder who places the Library under this License may add an explicit geographical
 distribution limitation excluding those countries, so that distribution is
 permitted only in or among countries not thus excluded. In such case, this
 License incorporates the limitation as if written in the body of this License.
 13. The Free Software Foundation may publish revised and/or new versions of
 the Lesser General Public License from time to time. Such new versions will
 be similar in spirit to the present version, but may differ in detail to address
 new problems or concerns.
 Each version is given a distinguishing version number. If the Library specifies
 a version number of this License which applies to it and "any later version",
 you have the option of following the terms and conditions either of that version
 or of any later version published by the Free Software Foundation. If the
 Library does not specify a license version number, you may choose any version
 ever published by the Free Software Foundation.
 14. If you wish to incorporate parts of the Library into other free programs
 whose distribution conditions are incompatible with these, write to the author
 to ask for permission. For software which is copyrighted by the Free Software
 Foundation, write to the Free Software Foundation; we sometimes make exceptions
 for this. Our decision will be guided by the two goals of preserving the free
 status of all derivatives of our free software and of promoting the sharing
 and reuse of software generally.
   NO WARRANTY
 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
 THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
 "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
 BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
 FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
 OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
 THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
 OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
 OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 END OF TERMS AND CONDITIONS
 How to Apply These Terms to Your New Libraries
 If you develop a new library, and you want it to be of the greatest possible
 use to the public, we recommend making it free software that everyone can
 redistribute and change. You can do so by permitting redistribution under
 these terms (or, alternatively, under the terms of the ordinary General Public
 License).
 To apply these terms, attach the following notices to the library. It is safest
 to attach them to the start of each source file to most effectively convey
 the exclusion of warranty; and each file should have at least the "copyright"
 line and a pointer to where the full notice is found.
 <one line to give the library's name and an idea of what it does.>
 Copyright (C) <year> <name of author>
 This library is free software; you can redistribute it and/or modify it under
 the terms of the GNU Lesser General Public License as published by the Free
 Software Foundation; either version 2.1 of the License, or (at your option)
 any later version.
 This library is distributed in the hope that it will be useful, but WITHOUT
 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
 FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more
 details.
 You should have received a copy of the GNU Lesser General Public License along
 with this library; if not, write to the Free Software Foundation, Inc., 51
 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Also add information on how to contact you by electronic and paper mail.
 You should also get your employer (if you work as a programmer) or your school,
 if any, to sign a "copyright disclaimer" for the library, if necessary. Here
 is a sample; alter the names:
 Yoyodyne, Inc., hereby disclaims all copyright interest in
 the library `Frob' (a library for tweaking knobs) written
 by James Random Hacker.
 < signature of Ty Coon > , 1 April 1990

 GNU LESSER GENERAL PUBLIC LICENSE
 Version 3, 29 June 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies of this license
 document, but changing it is not allowed.
 This version of the GNU Lesser General Public License incorporates the terms
 and conditions of version 3 of the GNU General Public License, supplemented
 by the additional permissions listed below.
   0. Additional Definitions.
 As used herein, "this License" refers to version 3 of the GNU Lesser General
 Public License, and the "GNU GPL" refers to version 3 of the GNU General Public
 License.
 "The Library" refers to a covered work governed by this License, other than
 an Application or a Combined Work as defined below.
 An "Application" is any work that makes use of an interface provided by the
 Library, but which is not otherwise based on the Library. Defining a subclass
 of a class defined by the Library is deemed a mode of using an interface provided
 by the Library.
 A "Combined Work" is a work produced by combining or linking an Application
 with the Library. The particular version of the Library with which the Combined
 Work was made is also called the "Linked Version".
 The "Minimal Corresponding Source" for a Combined Work means the Corresponding
 Source for the Combined Work, excluding any source code for portions of the
 Combined Work that, considered in isolation, are based on the Application,
 and not on the Linked Version.
 The "Corresponding Application Code" for a Combined Work means the object
 code and/or source code for the Application, including any data and utility
 programs needed for reproducing the Combined Work from the Application, but
 excluding the System Libraries of the Combined Work.
   1. Exception to Section 3 of the GNU GPL.
 You may convey a covered work under sections 3 and 4 of this License without
 being bound by section 3 of the GNU GPL.
   2. Conveying Modified Versions.
 If you modify a copy of the Library, and, in your modifications, a facility
 refers to a function or data to be supplied by an Application that uses the
 facility (other than as an argument passed when the facility is invoked),
 then you may convey a copy of the modified version:
 a) under this License, provided that you make a good faith effort to ensure
 that, in the event an Application does not supply the function or data, the
 facility still operates, and performs whatever part of its purpose remains
 meaningful, or
 b) under the GNU GPL, with none of the additional permissions of this License
 applicable to that copy.
   3. Object Code Incorporating Material from Library Header Files.
 The object code form of an Application may incorporate material from a header
 file that is part of the Library. You may convey such object code under terms
 of your choice, provided that, if the incorporated material is not limited
 to numerical parameters, data structure layouts and accessors, or small macros,
 inline functions and templates (ten or fewer lines in length), you do both
 of the following:
 a) Give prominent notice with each copy of the object code that the Library
 is used in it and that the Library and its use are covered by this License.
 b) Accompany the object code with a copy of the GNU GPL and this license document.
   4. Combined Works.
 You may convey a Combined Work under terms of your choice that, taken together,
 effectively do not restrict modification of the portions of the Library contained
 in the Combined Work and reverse engineering for debugging such modifications,
 if you also do each of the following:
 a) Give prominent notice with each copy of the Combined Work that the Library
 is used in it and that the Library and its use are covered by this License.
 b) Accompany the Combined Work with a copy of the GNU GPL and this license
 document.
 c) For a Combined Work that displays copyright notices during execution, include
 the copyright notice for the Library among these notices, as well as a reference
 directing the user to the copies of the GNU GPL and this license document.
      d) Do one of the following:
 0) Convey the Minimal Corresponding Source under the terms of this License,
 and the Corresponding Application Code in a form suitable for, and under terms
 that permit, the user to recombine or relink the Application with a modified
 version of the Linked Version to produce a modified Combined Work, in the
 manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
 1) Use a suitable shared library mechanism for linking with the Library. A
 suitable mechanism is one that (a) uses at run time a copy of the Library
 already present on the user's computer system, and (b) will operate properly
 with a modified version of the Library that is interface-compatible with the
 Linked Version.
 e) Provide Installation Information, but only if you would otherwise be required
 to provide such information under section 6 of the GNU GPL, and only to the
 extent that such information is necessary to install and execute a modified
 version of the Combined Work produced by recombining or relinking the Application
 with a modified version of the Linked Version. (If you use option 4d0, the
 Installation Information must accompany the Minimal Corresponding Source and
 Corresponding Application Code. If you use option 4d1, you must provide the
 Installation Information in the manner specified by section 6 of the GNU GPL
 for conveying Corresponding Source.)
   5. Combined Libraries.
 You may place library facilities that are a work based on the Library side
 by side in a single library together with other library facilities that are
 not Applications and are not covered by this License, and convey such a combined
 library under terms of your choice, if you do both of the following:
 a) Accompany the combined library with a copy of the same work based on the
 Library, uncombined with any other library facilities, conveyed under the
 terms of this License.
 b) Give prominent notice with the combined library that part of it is a work
 based on the Library, and explaining where to find the accompanying uncombined
 form of the same work.
   6. Revised Versions of the GNU Lesser General Public License.
 The Free Software Foundation may publish revised and/or new versions of the
 GNU Lesser General Public License from time to time. Such new versions will
 be similar in spirit to the present version, but may differ in detail to address
 new problems or concerns.
 Each version is given a distinguishing version number. If the Library as you
 received it specifies that a certain numbered version of the GNU Lesser General
 Public License "or any later version" applies to it, you have the option of
 following the terms and conditions either of that published version or of
 any later version published by the Free Software Foundation. If the Library
 as you received it does not specify a version number of the GNU Lesser General
 Public License, you may choose any version of the GNU Lesser General Public
 License ever published by the Free Software Foundation.
 If the Library as you received it specifies that a proxy can decide whether
 future versions of the GNU Lesser General Public License shall apply, that
 proxy's public statement of acceptance of any version is permanent authorization
 for you to choose that version for the Library.
