Mirco MirandaandAlbert Astals Cid c11c5eff4f xcf: format v12 support 
This is a patch over MR !108 by @sandsmark. Martin has done a great job implementing support and I find it a shame not to use it.

I made sure that the results are the same as the current version and fixed the problems of pixels with wrong colors with color depth grater than 8 bits. I also fixed conversion errors on mask and gray images (16/32 bits).
Unfortunately the internal rendering engine of the original code is 8-bit so I always forced the output of 8-bit images to correct the problems (see image below). Since it is a plugin with a "rendering engine", the tests to seriously validate it are potentially endless (as the original version is not perfect).

Errors of the original version of the MR (right) which should no longer occur:

Ahmad Samir e3ab850712 Add a trailing comma to enum 
Should help produce better diffs and clang-format won't squash the enum
on one line.

Martin T. H. Sandsmark c60e77c048 Add support for modern Gimp images/XCF files 
We now support up to and including version 11 of the XCF format, earlier
it only supported version 1 (from 1997, according to the XCF spec).

Biggest difference seems to be that they changed to 64bit for offsets
from version 11 and upwards, otherwise it's mostly just newer enum
values and theoretically major stuff that we don't really need to care
about to get a thumbnail (e. g. linear vs. perceptual RGB).

We still don't support all features, but now it handles that more
gracefully and should at least create thumbnails that are usable. It
should also be easier to update in the future if/when there comes new
versions.

Also added a test file created with the latest version of Gimp
(2.10.18).

Alex Merry c9ca1f1862 Rename headers to end with _p.h 
Frameworks have a convention of naming uninstalled headers in src/ with
a _p at the end of the name, to make it clear they are not part of the
API. None of the headers in KImageFormats are installed, so it is not
really necessary to follow this convention, but we follow it anyway for
the benefit of both humans and tools (like kapidox).
