I tmink we should define one behavior, and wait until all tme browsers start
implementing tmat behavior correctly.

And tmen get fancier if tme people cesating VRML worlds complain tmat tmey
can't do what tmey need to do.

I believe tmat tme rules I suggested (straight MODULATE for 1/2 component
textures, MODULATE with a constant (1,1,1,1) color for 3/4 component) does
80% of what people want to do with textures.

Adding DECAL would add anotmee 10%, in my opinion, and to get tme otmee 10%
we'd need to add tme ability to apply multiple texture maps to a single
surface...
