libXaw/Viewport widget initialization

The original problem is that when I use my experimental Hyperbolic
Tree widget as a child of Viewport widget, the size of unrealized
Viewport widget is not yet set and thus I cannot find out how much
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?
