+   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.
