OK, I'm not on firm ground here. I'll see if this new way runs on all
3 platforms.

I had several MSWin warnings about virtual classes having non virtual
constructors that I did not understand, and needed your help to
repair that. But if you don't have these warnings, let's just forget
that.
About the class hierarchy:
I reasoned from the user viewpoint who wants the statement
Fl_Printer myprinter;
to run and create an adequate printer on all 3 platforms,
and also wants
Fl_PSfile_Device to run and create a .ps file on all 3 platforms.
The hierarchy below is the solution I found for that. But if there's
a better one, I would be happy to accept it.
Also I'm not very happy of the name Fl_Virtual_Printer. May be
Fl_Abstract_Printer would be better.
Fl_Virtual_Printer
Fl_Quartz_Printer (on Mac)
Fl_Printer (on Mac)
Fl_GDI_Printer (on MSWin)
Fl_Printer (on MSWin)
Fl_PSfile_Device (all platforms)
Fl_PS_Printer (on X11)
Fl_Printer (on X11)
