a05a62d9d0 Rework subcompositor damage culling and use a back buffer in the pict renderer 
Note that the EGL renderer has been broken by these changes.

`finish_render'.  Add `cancel_completion_callback'.  Remove
`cancel_presentation'.
(struct _BufferFuncs): Add `is_buffer_opaque'.
* egl.c: Note that the EGL renderer is currently broken.

fences.
