winex11: Track the client colormap separately. 

If a window with an OpenGL surface attached is reparented as a child window,
and then reparented as a top-level window, so that its whole window is
destroyed and then recreated, it will be recreated with the colormap of its
child window, which more than likely has a different visual. This violates
the X11 specification, which states that a window's colormap must have the
same visual as the window itself, and causes the X server to return BadMatch
to the CreateWindow request.
