This is OpenGL painting *two* textured triangles, waaaaaay below the 
demands of modern 3D games. It had *better* be ludicrously fast ;-).

Actually, you'll take the biggest hit from mode changing (i.e. disabling 
and enabling texturing and lighting). I wouldn't expect that to be 
problematic (or even noticeable, unless you're getting FPS in the three 
digits), but if it is, it might actually help to create a plain-white 
texture and texture the cube with it.

OTOH you can also reclaim a little performance by not clearing the color 
buffer.
