Allow graphics events to be processed while pause is active (bug #53729) * util.h/cc (octave::sleep): Add second argument "do_graphics_events" that defaults to false. Depending on do_graphics_events, unlock the graphics mutex and call gh_manager::process_events after each time laps. When the requested time is infinite, call octave::kbhit after each time laps and interrupt if a character was typed. * sysdep.cc (Fpause): Without argument, set time value to inf. Call octave::sleep with the second argument true. Document that graphics events are handled even though the program is paused.
