I'm trying to draw images onto my GUI windows' textures (which are quads).
I figured it'd be a good idea to draw onto separate layers so I can safely rewrite text all over my topmost layer without worrying about remembering which graphics need to be drawn where on the artwork layer underneath. I was originally going to use separate entities for each layer, but then I read about multitexturing and figured it might simplify things. Everything seemed to be going fine until I tried to make the whole window translucent with EntityAlpha.
