// Fl_Font.H
// Two internal fltk data structures:
// Fl_Fontdesc: an entry into the fl_font() table. This entry may contain
// several "fonts" according to the system, for instance under X all the
// sizes are different X fonts, but only one fl_font.
// Fl_XFont: a structure for an actual system font, with junk to help
// choose it and info on character sizes. Each Fl_Font has a linked
// list of these. These are created the first time each system font
// is used.
