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.
-Most 2D drawing is implemented
-Missing shaders
-Missing all 3D
-Editor needs to be set on update always to be used, otherwise it does not refresh
-Large parts of editor not working
