that is, Fl::run() returns. The application can then follow
FLTK's normal termination path executing cleanup code that may be programmed
after termination of the event loop, and returning from main().
Function Fl::run_also_windowless() can be used instead of Fl::run() to keep
the event loop running also after all windows are closed, a feature the MacOS platform supports.
