// Two internal fltk data structures:
//
// Fl_Fontdesc: an entry into the fl_font() table.  There is one of these
// for each fltk font number.
//
// Fl_FontSize: a structure for an actual system font, with junk to
// help choose it and info on character sizes.  Each Fl_Fontdesc has a
// linked list of these.  These are created the first time each system
// font/size combination is used.
