softgpu: Make decal tex func more accurate.
...
Tested for all values of A * B + 0 * (255 - B), as well as A * 127 + B *
(255 - 127), and matches accurately. Spot checked other values, but not
exhaustively.

softgpu: Correct accuracy of MODULATE texfunc.
...
This matches hardware tests for every value of A * B.
Interesting that it's a different formula than alpha blend.

softgpu: Remove useless switch by UV gen mode.
...
They're all handled earlier now, and the switch is on a value & 3, so the
default wasn't even possible.

Oops, we need to subtract signed, but then clamp to unsigned.

This just reduces reliance on gstate directly, and should help keep things
consistent.

In case wsum_recip is nan or similar, we want to make sure we still
properly clip to minz/maxz.

For certain large values, it would overflow and continue looping
endlessly.
