Also, the comments for SCS seem a bit off. That's a pity, because
without comments I can't really see what the code does at first sight
:-). Looks like quite a few extra instructions though, are you sure
not more

- COS looks too complicated broken. If you'd want to get 2 with a
LOG2, you'd need 0.25 as source. But even using RCP instead, that's 5

Hi,
Getting proper SIN and COS wasn't as easy as it appeared. I had to make
make some changes to the fragment program code.
general FP changes:
- support HHH swizzle for vector

Hi,
Getting proper SIN and COS wasn't as easy as it appeared. I had to make
make some changes to the fragment program code.
general FP changes:
- support HHH swizzle for vector instructions.
- don't copy a source to a temp when it is not XYZW swizzled, but
combine the two and have the swizzle
