So we don't need pyOpenGL to replace Togl? Does the wxPython GLCanvas
replace Togl? Somehow we need to make calls from wxPython event handlers to
actually display/render a 3D image. I'm totally in the dark as to how this
is done. I've worked with the UI part of NVIZ (this is the overwhelmingly
greatest part, as you point out), but don't understand how the OGL calls are
actually made.
