I've been experimenting with the same thing (using PyGame)...

"Free" rotation is one of the big wins for using OpenGL to render
something like this, the other being "free" alpha blending...

I'm not an expert, but IIRC the texture co-ordinates are used to specify
which parts of the texture are drawn, and they can be used to mirror the
texture, but not rotate it.

That's probably the easiest approach, IMHO.
