softjit: Optimize common case bloom blending.
...
Bloom often uses fixed ONE + ONE, which is a lot less work for us. And
bloom often runs over and over again on pixels, so saving work is good.

softgpu: Add code for tracking GPU writes.
...
Unfortunately, it has a pretty noticeable speed impact, even at the basic
"assume everything's written" level. Compiled off by default, but at
least it's there.
Doesn't account for tests (i.e. alpha test skipping write) so still not
perfectly accurate.

samplerjit: Update nearest args, temp disable jit.
...
This temporarily disables jit for nearest, but refactors to use the new
arg structure. It now matches linear.

samplerjit: Create a separate fetch func.

This allows nearest to become more similar to linear, where it applies the
texture function.

softgpu: Skip processing scissored triangles.
...
If only one side was scissored (common), we might even put it on a thread,
which ended up as a lot of overhead. Gives 3-4% improvement in some
places.

These were drawing before, incorrectly, which caused artifacts.

Could do this also for nearest, might end up with a third set of functions
there for a direct sample lookup (for debug funcs.)

softgpu: Reduce mipmap fraction to 4 bits.
...
For CONST (and SLOPE with flat w), this produces accurate values.
SLOPE is still wrong in its handling of w, and AUTO seems to calculate
using a different and less accurate ramp. But they both produce values
with 16 steps, in any case.
