\class Fl_Counter
\brief Fl_Counter widget for Forms compatibility.
The Fl_Counter widget is provided for forms compatibility.
It controls a single floating point value.
\todo Refactor the doxygen comments for Fl_Counter type() documentation.
The type of an Fl_Counter object can be set using type(uchar t) to:
\li \c FL_NORMAL_COUNTER: Displays a counter with 4 arrow buttons.
\li \c FL_SIMPLE_COUNTER: Displays a counter with only 2 arrow buttons.
