The only time I've used the FBO extension is when I've got an OpenGL 
window open, e.g. for rendering a separate pick buffer so I can tell 
what the user clicks on. I don't know of a way to initialize GL without 
a window, although it's certainly possible to initialize GL without 
using GLUT. You can use wxPython's GLCanvas, for instance. But even 
GLCanvas expects a parent window.
