Does this object relate to pix_composite? or is this a osx only version?

Over the weekend I added a test Altivec function to pix_add. There's an #ifedf wrapped around a call to the processYUVAltivec() function in the standard scalar routine. After trying a few things this seems like a fairly simple way to implement Altivec and MMX. Can someone check the compile on Linux and Windows?
Also, there is a new object: pix_mix. It mixes two images together. Try it out, and have some fun.

If you mean pix_mix then, yes, it sort of relates to pix_composite, only it doesn't use the alpha to blend the images. it directly operates on the yuv or rgb values. also, there is no alpha channel in the yuv images.
the altivec pix_add function of course only applies to OSX.
i've attached an example patch for pix_mix. are others adding example patches to the CVS?
