X11_GL_GetVisual notices SDL_windowid and uses it, just as X11_CreateWindow 
does, so the problem reduces to letting SDL know about a window that some 
window manager already created, as Sam does in his gtk-demo:

	char SDL_windowhack[32];

Sam calls this a hack, and that's accurate.

I thought I'd be lazy and just modify Sam's demo to initialize and render 
with OpenGL, but it doesn't work that way.  You have to teach GTK (in this 
case) about OpenGL and I haven't discovered the one true way to do that.  
Here's one possibility:
