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.

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.

Rasterizer: Pre-divide vertex attributes by W

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.

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.

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.

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.
