The original problem is that when I use my experimental Hyperbolic

space I have available for layout.
I have the following patch in mind and it solves the problem for me.
Does it make sense or should I look for another solution?

That looks fine to me.
I do have one request though. If you are to contune with more Xaw work,
please ensure you do not adversely affect Xaw6.
Thanks.
