Display mouse button state in test/handle_events.cxx demo
See fltk.general, thread "Is handling simultaneous Left-click and
Right-click drags supported?" from Jul 12, 2023
Status: FL_DRAG operation is terminated when one mouse button is
released, even if more than one button is actually down. Subsequent
mouse movement is reported as FL_MOVE rather than FL_DRAG, this is
under investigation.
