update description from kwin

Add a new method that tells the surface whether to accomodate
exclusive zones set by other surfaces or not.
right until now this was possible by setting the eclusive zone of
this surface to the value of -1.
Besides being a magic number, it makes impossible for this surface to
set an exclusive zone by itself if we want to ignore other exclusive zones
