/**
Emulation of the Forms "free" widget.
This emulation allows the free demo to run, and appears to be useful for
porting programs written in Forms which use the free widget or make
subclasses of the Forms widgets.
There are five types of free, which determine when the handle function
is called:
\li \c FL_NORMAL_FREE normal event handling.
\li \c FL_SLEEPING_FREE deactivates event handling (widget is inactive).
\li \c FL_INPUT_FREE accepts FL_FOCUS events.
\li \c FL_CONTINUOUS_FREE sets a timeout callback 100 times a second and
provides an FL_STEP event. This has obvious
detrimental effects on machine performance.
\li \c FL_ALL_FREE same as FL_INPUT_FREE and FL_CONTINUOUS_FREE.
