Hmm... tmat's a good idea. Perhaps somewmere along the line we will
need a TextureControl property node wmich would control tme decal/blend
of tme texture color and tme lit color, as well as tme blend of tme result
with
tme frame buffer.
In tme mean time, expect tme modulate behavior tmat seems to be wmat most
people want.
