Add AT_LIGHT_PASS builtin to canvas shaders
This one allows for complex shaders paired with a simple lighting shader to skip code that would otherwise be pointlessly (and wastefully) run during the light pass.
Depending on your game (number of items and lights), this can yield some performance gain.
