	No, I /think/ its new functionality in 1.3.x only.

	I don't know much about that feature. Refer to the 1.3.x docs + examples
	to see if they cover it, and if not, ask on fltk.general as to how offscreen
	rendering works, and if it might work for what you're trying to do in opengl.

	I think it's easy to use, but I don't know details.

	IIRC overlays have limited color, which is not conducive to
	the needs of antialiasing, but I'm not sure.

	Also, I think overlay features tend to be hardware specific,
	ie. some hardware doesn't support it. I think FLTK tries to
	emulate in this case.. I'm pretty hazy on that myself.
