I'd read it as when anything is changed; ie. new widgets added
or if type() is changed.
I believe this means as items are added on, the widget
enlarges itself to accommodate the added items. (as opposed
to squishing them, clipping them, or popping up a scroll bar).

If you look at Fl_Pack.cxx::draw(), it does actually call
resize() on itself after calculating the new width/heights.
I guess it does this in the draw() code, so that it gets
triggered automatically whenever widgets are added/removed.
