...just tested 'em, and they seem much better so far...maybe not faster 
in osx(tho I was testing on a 720x480), but then that'll come with the 
altivec...I was pretty astonished to see that the old rgba conversions 
actually lightened the picture, and I could only chain together 2 
pix_rgba/pix_yuv's before noticeable color screw-ups occurred!

...I'm now migrating the altivec stuff that I've done so far into your 
new GemPixUtil.cpp that ya sent, so if you wanna commit it, go ahead, 
or just wait and I can do it when I get this stuff merged...
