    GDK GL context's should associate with "window->impl_window" not "window"
    
    In some layouts this inconsistency results in crashes in
    gdk_gl_texture_from_surface() since it uses gdk_gl_context_get_window() but
    the returned window is not the same as the one that is being painted so
    "window->current_paint.surface" is NULL. I saw this problem when packing a
    GdkGLArea into a GtkPaned.
