commit 2ed484817ef3a5084dc65a2ae1acdef551acd107
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Tue Jan 8 16:06:02 2013 +0000

    xlib/shm: Discard damage upon shm finish
    
    Both to make sure we do not leak the memory, but to also prevent
    _cairo_xlib_surface_put_shm() from operating upon the finished shm
    surface after the display is closed.
