[cross-posting this reply because it certainly seems relevant to both 
Pharo and Squeak]

This seems to me to be roundabout, and will make sure that any Mac 
version of OpenGL will be far slower than any Windows version.

What I'm not understanding is how the current OpenGL libs can render 
directly on the screen on a Mac, while the Igor's can't. The  Croquet 
OpenGL package appears to be grabbing something from the Baloon3D 
plugin, I think. Has anyone looked at how THAT tells OpenGL libs to 
render to the appropriate area on the system window?

primCreateRenderer: flags x: x y: y w: w h: h
<primitive: 'primitiveCreateRendererFlags' module:'B3DAcceleratorPlugin'>
