Henrik RydgårdandClaude Opus 5.5 68c9593fb6 SoftGPU: Apply the texture function to a span's four pixels in lanes

The four-pixel sampler now runs the texture function (modulate, decal,
blend, replace and add, with color doubling) on all four pixels at once,
one vector per channel, instead of GetTextureFunctionOutput per pixel.

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks
that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
