I could see making a fully flexible packing widget like an HTML table..

    I should probably review this TableBox widget in our Links pages, which sounds like it's exactly that..

	TableBox The TableBox manages a group of widgets that are arranged in rows and columns, making it easy to align many widgets next to each other [..]The whole project was inspired by HTML table and GTK+ table widget.

    I did research that a bit; unfortunately that widget is fltk2.

    I was unable to get the old fltk2 project to build on my machine, so I couldn't explore it.
    But I did make a very rough port that works with fltk 1.x, tossing the result on github
    in case anyone wants to try to fix it/take it further with a fork.

    The TableBox demo in my port runs and very interesting resizing behavior happens, but I don't
    think I got it fully working as intended. I can't remember fully how fltk2's layout() system
    worked, so it could be a problem with how I ported that.

    I think layout() was called on first drawing to reposition/size the widgets, and then
    Ialso called during any kind of resize().  I emulated that in the port, since TableBox
    overloads layout() to do its work, but not sure I got all that right; didn't have time
    to really dig in.
