The demo needs pyOpenGL so that it can draw stuff on the canvas.

NVIZ doesn't use OpenGL from Tcl. NVIZ itself (as opposed to the OGSF
library) only barely uses it at all: Togl, which is rougly analogous
to GLCanvas, and do_zoom.c, which sets up an off-screen "canvas". And
most of that is glX/wgl/agl rather than OpenGL proper.
