light_mask — GFX2D light op

使い方

Modulate an rgb image by an rgb light map: base * (ambient + light).

ambient is the light that reaches everything; ambient=1 with a black light map returns the base exactly, which is the identity the test suite pins.

The product is clipped to [0, 1]; the clipped amount is not returned. Both arguments should be in the same encoding — mixing an sRGB base with a linear light map is the second silent-error trap of this family, and the only defence is that both arguments are named.
