Stenzek 260d5b7aa7 BPMemory: Handle fog configuration where both A and C are infinity/NaN ... The console appears to behave against standard IEEE754 specification here, in particular around how NaNs are handled. NaNs appear to have no effect on the result, and are treated the same as positive or negative infinity, based on the sign bit. However, when the result would be NaN (inf - inf, or (-inf) - (-inf)), this results in a completely fogged color, or unfogged color respectively. We handle this by returning a constant zero for the A varaible, and positive or negative infinity for C depending on the sign bits of the A and C registers. This ensures that no NaN value is passed to the GPU in the first place, and that the result of the fog calculation cannot be NaN.		2018-02-01 17:40:39 +10:00
