xserver-multidpi/render/picturestr.h
Stuart Kreitman d4a101d4ef Integration of DAMAGE-XFIXES branch to trunk
https://freedesktop.org/bugzilla/show_bug.cgi?id=859
These RENDER changes come from the experimental freedesktop tree formerly
    known as "Xserver". Partly motivated by compatibility with DAMAGE as
    pulled from that tree, also some of the code just is better
    implemented.
Modified Files: filter.c picture.c picture.h picturestr.h
