Compute FIXA/FIXB blends like the GE
...
The GE's blend terms are floor((2c+1)(2f+1)/1024), which truncates, while the
hardware multiplies by f/255 and rounds, so every pass of a fixed color blend
chain came out up to a level brighter. God Eater Burst's bloom is many such
passes and ended up far too bright.
For additive FIXA/FIXB blends that aren't just 0 and 0xFFFFFF, the shader
now computes the src term exactly and lowers it by 0.5 - (2B+1)/1024, and the
blend constant is the GE's dst factor (2B+1)/512, so the hardware's rounding
of the sum lands on the GE's floor (except where the src term would go below
zero). Blend constants are passed as floats to make that possible.

Apply the pixel masks to clears in the hardware backends
...
On the PSP the color and alpha/stencil write masks apply to clears like to
drawing (gpu/stencil/writemask, ppsspp-re geprobe exp254). Clear-mode draws
now take the same per-channel heuristic as other draws, and a clear with RGB
masked is drawn rather than done as a hardware clear.
