Prevent creating a gl_drawable for a window as type DC_GL_WINDOW if the window has children since DC_GL_WINDOW does not support clipping.
If a parent window is encountered of type DC_GL_WINDOW then recreate the gl_drawable.

The main issue I have is with the name "have_child". It's too… definitive. When it's passed as false (from X11DRV_WindowPosChanged()), that doesn't mean there definitely aren't children, just that we don't know definitively whether there are or aren't. (If it were definitive, then the GetWindow(…, GW_CHILD) check wouldn't be needed.)
Perhaps "known_child"?
Otherwise, looks good to me.
