That video doesn't show Linux being ahead. I didn't see anything on
there, for example, where a stack of filters were applied to images in
real time (so, for example, if you were doing, say, a gaussian blur,
followed by an edge enhancement, followed by swirling distortion, you
could go back and change parameters on the gaussian blur and have the
image instantly update). Same for video--can you specify a stack of
image filters and transforms, and have them apply to video in real time
(complete with adjustments to any of the filters applying in real time?).
What that video shows is a lot of effects that look cool, but are among
the simplest to do with OpenGL. Xgl is capable of more interesting
stuff, but you don't see it on that video. It still has a ways to go to
catch up to OS X, though.
