/* 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.
