Are you sure about this ? I thought there wernt concepts of '2D' and '3D'
in OpenGL - you just provide a transformation matrix, and if that happens to
be 'flat' so that the points get mapped onto one plane then you have 2D and
the library knowns nothing about it.

Somewhat irrelevent - GLUT allows you to open and render into multiple windows,
so any implementation oif GLUT will let you do this. If people buy cheap
harrdware that does a crap job of rendering it then thats not our fault or
our problem. The top layers should be independent of the hardware. After all
a lot of systems will be using something like Mesa anyway as they dont have
hardware GL. Its a bonus if it exists, but the fact that it doesnt or is
badly implemented shouldnt bother us unduly.

Maybe - but all we want is a portable way to throw data at the screen, which
it provides. It would make a Windows port far easiier for starters, which has
to be a big bonus.
