[Glamor] Wayland / Glamor DDX?

[He Junyan]

If  I do not misunderstand, you want an implementation in glamor to 
support XWayland,  just like
the work of xwayland branch in xf86-video-intel. Using Glamor to 
generate the textures for wayland
to composite will decrease the work for specific DDX's modification and 
can still solve the legacy
problem between X and wayland. It seems a good idea, the effect should 
be estimated.
