I am sure that this is caused by the viewport limit of Apple's OpenGL 
software renderer.

It is possible to render a larger image by tiling it into smaller 
rectangles to be drawn separately, using Q3DrawContext_SetPane and 
Q3Camera_SetViewPort.  Another possible workaround would be to make a 
large window, with coordinates that put it off the screen, render to 
that window, and get the image using glReadPixels.

It is possible that a future release of Mac OS X will include a more 
capable software renderer.
