[Xorg] XComposite, XDamage Extension with Xvideo or GL

[Amir Bukhari]

Redirect OpenGL application to backing store pixmap does not work with
Composite Extension (in Manual Mode) (Xserver always draw).
Is GLX use a wrapper functions for GC Operations, which let the Deron
Johnson hacks of GC wrapper functions in Composite extension not work OR
there is others reason? We use it by project Looking Glass.
Note that most GLX modules come with graphic card, which we could not hack
it directly.

Xvideo uses the overlay feature of the video cards to draw the video on the
screen, which bring trouble with composite extension. I heared there is a
discussion about how to get Xvideo to work with Composite extension, is that
right?
