// This file is "work in progress".  The main parts have been copied
// from fluid's print_panel{.fl|.h|.cxx} and hand-edited to produce
// a working version w/o global variables.  The intention is to move
// all static variables into an own class, and to name this class
// Fl_Printer_Chooser or similar...
//
// Todo:
//
//   -  Currently preferences can't be saved, and there are options that
//      are not yet used for printing.
//   -  This file can only be used as an include file in Fl_PS_Printer.cxx
//   -  The use of static variables should be avoided.
//   -  Probably much more ...
