Each triangle of a quad has its own UV planes, which a sprite built from the
corners doesn't reproduce. Textured triangle rectangles now only become
sprites in through mode with nearest filtering. Gears of Destiny's text boxes
become bit exact against the PSP, and no dump compared gets worse.

DrawSprite samples texel centers, but the GE's sprite UV planes usually land
slightly off them, which bilinear filtering shows: on most sprite sizes every
pixel blends its neighbors (gpu/probe exp87). Bilinear sprites now go through
the plane path. Gallery Fake's dump becomes bit exact.

Strips, fans and triangle pairs that form rectangles are drawn as sprites,
but a sprite's first column is (x + 6) >> 4 and a triangle's (x + 7) >> 4.
For a left edge 9/16 into a pixel, draw them as triangles (NBA 2K13's menu
boxes, now 99.99% exact against the PSP).

A white vertex color still gets doubled, and so does replace. Found with
gpu/probe exp53.

The GE samples a pixel's texture coordinates at its center, so a 1:1 sprite
starting at u0 shows texel floor(u0 + 0.5) first (floor(u0 - 0.5) when
mirrored). The fast path truncated u0, half a texel off for fractional UVs.
Measured with gpu/probe; integer UVs are unaffected.

- Flush() on an empty queue now trims the state and CLUT rings, since its
callers flush because one is full and push right after.
- BinQueue::Full() uses >=, so an overshoot can't go unnoticed.
- IsExactSelfRender compares against the target the queued draws were
binned for, not gstate, which already has the next one during a flush.
- A depth test without depth writes marks the depth buffer as read.
- The DarkStalkers untextured sprite recomputes the binner state around it.

Performance impact is minimal because sprites that require depth/fog are relatively rare, and the fallback still uses the per-pixel rectangle loop (not the full triangle rasterizer)
* samplerjit: Remove unused x/y parameters.
Still need to tune the accuracy of filtering, but those were not the
right way.
* softgpu: Better approximate slope mip level mode.
This isn't exactly right, but it's closer.
* softgpu: Calculate auto from largest difference.
Direction shouldn't matter.
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.
