Textures with a color palette

[stucky77]

I was thinking the same thing about being able to edit them. But there are literally no color values, it's only black and white, but it is an rgb image. I'll attempt to insert a black and white rgb image to test what happens. But that limits me a lot obviously.

Oh, and I was incorrect earlier about there only being info in the red channel. That was from a prior dump with an older version. Sorry.
