Henrik RydgårdandClaude Opus 5.5 d7a96875fb Lighting: Use the GE's approximate pow for specular, diffuse and spot ...

The GE computes these powers as exp2(e * log2(x)), with log2 and exp2
each a straight line between powers of two (Mitchell's approximation),
and only uses the top 4 bits of the specular coefficient's mantissa.
Through a highlight's falloff a true pow is 10-30 steps of 255 brighter
at the exponents games use. Measured in gpu/lighting/specular.
