No, writing code for YUV colorspace is not something platform specific.
If the scenario you are painting happens, then these algorithms will be
available for YUV colorspace only, but on every platform.
(unless, of course, you write them in ALTIVEC).

Finally, to bring a real world example, I am happy that Mark didn't
write GEM platform specific for SGI's ... we all know why.
Platform specific code is bad and should be minimized.

I think that Daniels thoughts about how to handle all of this are
very interesting ..
