/**

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.
|
|
<P>There are five types of free, which determine when the handle
|
|
function is called: </P>

<P>An FL_INPUT_FREE accepts FL_FOCUS events. A FL_CONTINUOUS_FREE sets
|
|
a timeout callback 100 times a second and provides a FL_STEP event,
|
|
this has obvious detrimental effects on machine performance.
|
|
FL_ALL_FREE does both. FL_SLEEPING_FREE are deactivated.
