Now I need a whole new event-loop.

ImageFactory works.
I had to customize FreeGlut to share the HWND window handle that it creates when it opens the main Window. From that I can call wglCreateContext and make that rendering context current. I'm not sure how to get OpenGL rendering context without ever opening an Window....
Anyway, ImageFactory is now dependent on data that must be requested from the UpperDeck, but I've run into insurmountable system-messaging bugs.

Currently, the Toy uses FreeGlut to manage windowing, keyboard, etc.
I am now convinced that the main-loop of Glut breaks Swing, and maybe all Java events. I suspect that the system messages are held up somehow, and are only passed along after the "main window" closes.

The irony is that I'm not going to use the FreeGlut main loop, Swing, or even a screen window. But for testing etc, I need a GUI for control and communication.
So I have to dive into replacing the main loop before I wanted to.
Dang.

Oh, and there are still bogus exceptions thrown from within the Nvidia drivers at "exit". These propagate up and crash the JVM.

Dang again.
