OpenGL Contexts in Panther

I'm trying to render graphics into a Quartz context created by CGGLContextCreate, but I have found precious little documentation of its behavior, and no sample code to speak of.

To the routine I am passing the context returned to me by aglCreateContext (a double buffering context OpenGL context whose drawable is set to a window). I pass in the size of my viewport and use NULL for the color space (which is supposed to choose the default RGB color space).

I've tried drawing the Quartz graphics before and after the call to aglSwapBuffer but the Quartz Graphics don't show up.

Are there limitations to the support for GLContexts in Panther? (can they only be used with CGL contexts, full screen contexts, only if the software renderer is being used... something like that?)

If I'm using a double buffered GL context.. should I draw the Quartz graphics before or after the buffers are swapped?
