OpenGL and raster graphics

Does anyone out there have any ideas about raster graphics and openGL? I have heard that the
openGL raster functions aren't real fast.
For anyone been using openGL for 3D, what have you done about 2D? Does openGL suffice, or have
you devised a new solution?

Thanks, that helps us alot. Hearing that a professional game uses the same gives us alot more faith in it now.

Thanks for such a precise answer :). As Bryan said, that's given me a huge injection of faith in the OpenGL rasteriser.
The question was in relation to working out what to use for 2D GUI overlays in a 3D game, so knowning that the OpenGL rasteriser is quick with acceleration is exactly what I wanted to hear.

So yeah, you can totally use hardware accelerated OpenGL for 2D, I am assuming you are wondering about your game GUI or maybe thinking about doing a top down game. We used OpenGL for all the GUI's in Starsiege, Tribes and Tribes2 and it worked great. If you look at the DirectX8 spec you'll see they got rid of DirectDraw and assume you'll be using D3D for your 2D stuff.
