+// 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.
