After calling the primitive you can use any OpenGL commands to draw directly into it using the hardware renderer. I don't see a good reason why you would not want to use it.

I'm currently also experimenting with this (under Linux) and it looks like this does not fully work on my system - the
OpenGL output seems to be displayed for a very short moment, and then only teh Squeak desktop is visible again.
Of course, it's nice to have the platform-dependent part within the primitive, but at least for Windows and Linux/X11
creating an OpenGL context is not really difficult, so since we already have platform-dependent OpenGL subclasses
anyway, there is no strong reason to keep the context creation stuff in primitive code.
