Rethinking LDraw for modern hardware and software

[Philippe Hurbain]

I think I mentioned it before but I'm very much in favor of only using geometry based patterns on flat surfaces. Favoring the use of textures for curved ones. 

And allowing png's to use ldraw colors as their pallet (including #16) would solve the one downside of this.

One thing not currently addressed by texmap is printed metallic colors. Not sure also that it works fine for blended opaque+transparent parts.
