9d6de98ed9 softgpu: Correct drawing outside TL of rectangle.
If the start coordinate was something like 51.75, we were incorrectly
drawing to 51.  This can be seen in the Metal Slug intro (#15755.)

dc90a5a851 softgpu: Avoid projecting textures in common case.
Several games appear to intentionally set the matrix flat.

6282f8b05f softgpu: Expand texture coords to include q.
We'll need this to correctly project.

8376176b2f softgpu: Split clippos out of rasterization vert.
We don't use it, except w, at all in rasterization, so no need to keep it
in the bin queue.

b3c0f177e2 softgpu: Save last tc/normal in vertex reading.
Matches PSP behavior, reusing last set values.

c47d7eab38 softgpu: Simply 5551 blending fast path.
Since it only supports multiply and add, let's just stick with that.

a4c3718431 softgpu: Optimize rectangle sampling/blending.
Sometimes the vertex color or alpha can allow us to optimize away some
multiplication.

7d4aa3eb2d softgpu: Correct line early z checks.
Was looking at completely wrong pixels, hadn't removed subpixels yet.

1be5f1670c softgpu: Remove mostly unused screen offset state.
This is now already cleaned up from coords, so no need to cache it.

167213c746 softgpu: Cache texture bufws at 16 bit.
Reducing the size of state a bit.

b2e6a086dc 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.

8a6e8066bf softgpu: Store vertex colors as packed RGBA8.
No need to keep it expanded at 4x the space for both colors.

b90fc7137f 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.)

15d5fa48f7 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.

18c9a4d9c9 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.

1d0936ea79 Debugger: Improve drawing range in softgpu.
We don't always want all of region, particularly if scissor is a regular
screen size.  This improves debugging in GoW.

Filtering is still not perfect but this makes different orientations
better.

cc6491342e softgpu: Prepare dedicated rectangle path.
We're still sometimes using the slow rect-as-triangles path, let's do
something faster.  As a first step, just handle binning.

a66377fdf1 softgpu: Remove offset from screenpos.
This simplifies tighter calculations, and reduces the common magnitudes
we'll be dealing with.

85cb4101dc softgpu: Cleanup todos on perspective correctness.
Only the texture appears to be perspective corrected.  Color is simply
linear.

76f9103e97 softgpu: Add a table and initial dirty flags.
Not actually using the dirty flags to skip state, but have moved to
Execute_* functions and everything else like other graphics backends.

c0c3f7284a softgpu: Avoid flush texturing from stride.
This generally detects overlap more accurately using a dirty rectangles
approach.  Also detects render to self much more accurately, including
with depth.
