/* Video should be clipped to the intersection of the window cliplist

and the client cliplist specified in the GC for which the video was

|
initialized. When we need to reclip a window, the GC that started
|
|
the video may not even be around anymore. That's why we save the
|
|
client clip from the GC when the video is initialized. We then
|
|
use xf86XVUpdateCompositeClip to calculate the new composite clip
|
|
when we need it. This is different from what DEC did. They saved
|
|
the GC and used its clip list when they needed to reclip the window,
|
|
even if the client clip was different from the one the video was
|
|
initialized with. If the original GC was destroyed, they had to stop
|
|
the video. I like the new method better (MArk).
|
|
|
|
This function only works for windows. Will need to rewrite when
|
|
(if) we support pixmap rendering.
