Assume that we have an application with a subwindow using a different visual
than its parent (so that the parent cannot have the subwindow's colormap), but
that we want the subwindow's colormap to be installed whenever the parent has
the colormap focus (even if the subwindow does not have focus at the time).

For the confused, this would be useful in some kinds of imaging applications.

Questions:

1.  Is there some way under the current ICCCM to accomplish this?  If so, how?
2.  If there is no way to accomplish this, what kind of effort would it take
    to get this capability added?

WM_COLORMAP_WINDOWS is almost there but it appears that the colormap will only
be installed when the focus is directly on the subwindow.

Auxiliary question:  Which window managers, if any, currently support
WM_COLORMAP_WINDOWS?

Please answer via email.
