Henrik RydgårdandClaude Opus 5.5 f2bc80e66e SoftGPU: Signed doubled inverse alpha blend factors
DOUBLEINVSRCALPHA and DOUBLEINVDSTALPHA are 255 - 2a without a clamp: for
a >= 128 the factor is negative and its term subtracts,
-(((2c + 1) * (2|f| + 1)) >> 10), with only the sum clamped. Measured with
every factor and equation against a CPU-filled destination (gpu/probe
exp116, all exact). The x86 jit clamps the factors at 0, so these blends
use the C++ pixel function.
