/* For a nicer looking browser under linux/unix, call fl_register_images()
(If you do this, you'll need to link with fltk_images).
That's required for the preview option of the GTK filechooser.
In the unlikely situation where no native filechooser is found on
the active Linux system, FLTK reverts to using its own file chooser
(Fl_File_Chooser) which looks best if you also call
Fl_File_Icon::load_system_icons().
None of that is useful for the native file chooser under macOS or Windows.
