[PATCH 5/8] glamor: Split the XV code into XF86-dependent parts and generic.

Eric Anholt eric at anholt.net
Mon May 5 13:09:10 PDT 2014


I want to expose this from Xephyr as well, both to be able to test XV
changes rapidly, and beause the XV passthrough to the host's overlay
really doesn't work out well when we glXSwapBuffers() over the
colorkey.
