File cairo-1.0.2-depth-fix-1.patch of Package cairo

This fixed a problem with libpixman getting the depth wrong for some
16bpp image formats but still render things correctly. Using
surface->depth instead of image->depth for the ximage was a quick way to
avoid this problem.

It's not the appropriate fix and should probably not go upstream.
libpixmap should be fixed if it hasn't already.
