No, I didn't try that.  I was trying to make an uncompressed movieplayer
and made a bunch of tests to see where the bottlenecks are.
So I have some other programs running on OS X but didn't attempt
to build mplayer there!  Just mentioned Apple to point out that,
if texture performance is a driver issue, it's an issue with
drivers on at least two unrelated platforms.

One possibility: it could be that the textures are loaded in
non-sequential order, such that cache size matters.
