/**
* @brief Provides an OS-independent interface to printing.
*
It allows to use all FLTK drawing, color, text, and clip functions, and to have them operate
on printed page(s). There are two main, non exclusive, ways to use it.
<ul><li>Print any widget (standard, custom, Fl_Window, Fl_Gl_Window) as it appears
on screen, with optional translation and scaling. This is done by calling print_widget()
or print_window_part().
<li>Use a series of FLTK graphics commands (e.g., font, text, lines, colors, clip) to
compose a page appropriately shaped for printing.
</ul>
In both cases, begin by start_job(), start_page(), printable_rect() and origin() calls
and finish by end_page() and end_job() calls.
