/* Fl_Scalepack
This is similar to an Fl_Pack, but instead of the pack resizing
itself to enclose its children, this pack resizes its children to
fit itself. Of course, this only works well with highly flexible
widgets, but the task comes up often enough to warrent this class.
If any child happens to be the resizable() widget, it is given half
of the available area, with the other widgets packed around it in
the remaining space.
