/**
  The Fl_Value_Output widget displays a floating point value.
  If step() is not zero, the user can adjust the value by
  dragging the mouse left and right.  The left button moves one step()
  per pixel, the middle by 10 * step(), and the right button by
  100 * step().
  <P>This is much lighter-weight than
  Fl_Value_Input because it contains no text editing code or
  character buffer. </P>
