I think all the GUI toolkits insist on running their own mainloop,

You can run OpenGL or SDL inside their own windows. I think this is
the way to go.

Doodling over a GUI is of limited use anyway. Simply having a canvas
you can interactively draw on from IRB is a neat thing. It was one of
the features I'd planned for FXIrb, but I don't have the time to
maintain that these days :(
