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 r
note to self: don't post this late...

I didn't look too closely at this but I've a couple of comments.
- 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
instructions before performing the sine, for something
