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.

No need to keep it expanded at 4x the space for both colors.

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: 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.

GE Debugger: Fix crash stepping with large tex.

Some math was overflowing in allocations, and it would allocate zero
bytes. Let's just refuse textures more actively.

We don't always want all of region, particularly if scissor is a regular
screen size. This improves debugging in GoW.

We're still sometimes using the slow rect-as-triangles path, let's do
something faster. As a first step, just handle binning.
