This is a bastardized version of Amulet 3, in which I have ripped out the
X/Windows/Macintosh layer of GEM and replaced it with FLTK, a cross platform
GUI building system.

The goal is to be able to seamlessly integrate Amulet into an FLTK application,
and also use FLTK widgets from Amulet, thus increasing Amulet's usefulness and
extending Amulet's abilities into an FLTK application.

Known problems that won't go away

 - FLTK does _no_ stippling of any kind as far as I can tell

 - Something is strange with interactors for Amulet menus, I have to have the
   pop-up window Fl::grab the events, but then I lose some of the nice standard
   menu abilities, such as closing your popup and bringing up the neighbor
   popup when you drag over to that Menubar item.
