	I've never tried, but apparently its non-trivial:
	http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=43
	http://www.opengl.org/resources/features/fontsurvey/

	Offhand, FTGL in that last link looks worth investigating. eg:
	http://ftgl.wiki.sourceforge.net/

	Also, there may be FLTK tricks to help do this.
	Perhaps FLTK's new 'offscreen rendering' functions can be used to draw
	aa'ed text to an offscreen buffer, and then these could be slapped into
	an opengl window with glDrawPixels() or somesuch. Some of the devs
	familiar with offscreen rendering might be able to weigh in on this.

	If you get something working, let us know!
