...right: I mean, we can't write altivec code for you to use, and
vice-versa for ya'll and MMX! Also, we use different codecs and
stuff, but that should all be transparent, anyway...

...don't worry: we're still here! Just got quiet for awhile during
a little break ;-)
...I think chris and I have come around to putting everything into
pix_*, but that means there will be alot of objects that don't have
rgba functionality, which is kinda useless on macs now; also, I think
it'd be to everyone's advantage to move to YUV processing, even if
there is a last minute conversion before texturing, because of the
reduced amount of data for manipulation, and the fact that most
codecs are decompressed to yuv, then converted to rgba anyway (see
libmpeg)...I'm also keen on the idea of having movie/film/video
objects that change color space based on messages sent to them, but
we've got alot of coding to make this all work...;-)
ok, end o'tirade/dreaming-out-load!
