The following small program shows that ValueOutput does not
behave regularly.
When I DRAG the main window: only ValueOutput changes the
background color. Although ValueOutput and ValueInput have
the same basic class Valuator.
Converting the program to fltk-1.3.x-r6980 shows: ValueOutput
of fltk-1.3 does not change the background color during a DRAG.
