3b78af904e Pica/Rasterizer: Textures seem to be laid out flipped vertically.
Not sure if this is a correct fix. Probably should instead change the decoding logic itself.

632655e292 Pica: Fix A4, IA4 and IA8 texture formats.
Both IA4 and IA8 had their component order mixed up. Additionally, IA4 used the wrong number of nibbles per texel. A4 skipped every second texel.

8369ee5803 Rasterizer: Pre-divide vertex attributes by W
Execute the division-by-W for perspective-correct interpolation of
values in the clipper, moving them out of the rasterization inner loop.

fe186d3a59 GPU: Bitwise texture swizzling
Replace the loop-based texture address swizzling code by a bit-twiddling
implementation, providing a very small speed up. Also simplify
addressing code.

2012e1420f Rasterizer: Common sub-expression elimination
Move the computation of some values out of loops so that they're not
constantly recalculated even when they don't change.

7e9bc85cc8 Clipper: Compact buffers on each clipping pass
Use a new buffer management scheme in the clipper that allows using a
bounded minimal amount of buffer space. Even though it copies more data
it is still slightly faster likely due to using less cache.

a320d1a5b4 Clipper: Avoid dynamic allocations
The triangle clipper was allocating its temporary input, output and work
buffers using a std::vector. Since this is a hot path, it's desirable to
use stack allocation instead.

d151d797b1 Vertex Shader: Zero OutputVertex to avoid denormals
Unused OutputVertex attributes were being left un-initialized. The
leftover garbage sometimes decoded as floating-point denormalized
values, causing fallbacks to microcode and massive slowdowns in the rest
of the rasterization pipeline even though the results were unused. By
zeroing the structure we ensure these attributes only contain harmless
zeros.
