This is now already cleaned up from coords, so no need to cache it.

softgpu: Reduce size of VertexData texture coords.
...
There's no real benefit to this with only two values.
Not much of a gain perf wise, but still good to transfer less data.

softgpu: Ignore stencil test mask in ALWAYS mode.

Small codegen improvement since we can directly use ref and avoid loading
the unmasked reference.

Could maybe even combine these into one large rectangle, but the main

softgpu: Correct accuracy of fog calculation.

This matches values from a PSP exactly, with the help of immediate mode
vertex values (since this directly allows specifying the fog factor
without any floating point math.)

softgpu: Restrict sprite fast path to throughmode.

Its UV checks already should have generally, but let's be safe. It
doesn't validate state like fog, etc.

softgpu: Check depth test early on simple stencil.
...
If we don't need to write stencil on sfail/zfail, we can do the depthtest
early, which allows us to more often skip texture sampling.
This gives a good improvement in Chains of Olympus.

softgpu: Clamp/wrap textures at 512 pixels.
...
A texture larger than 512 is "valid", but simply wraps/clamps at 512.
Importantly, the texture coords are still calculated at the specified
size, which can be up to 32768.

Some math was overflowing in allocations, and it would allocate zero
