Have Fl_Pack::draw() call Fl_Group::init_sizes() on its parent group.

Browse Source 
Fl_Pack::draw() sometimes resizes itself. This must be followed
by a call to Fl_Group::init_sizes() as indicated in that function's doc:
"If you rearrange the widgets in your group, call this method to register
the new arrangement with the Fl_Group that contains them."
