-/**
- * \file xm_surface.c
- * Code to allow the softpipe code to write to X windows/buffers.
- * This is a bit of a hack for now. We've basically got two different
- * abstractions for color buffers: gl_renderbuffer and pipe_surface.
- * They'll need to get merged someday...
- * For now, they're separate things that point to each other.
