TEXTBOX (display and set any value)

The most basic and flexible display meter is the TextBox,
a small entry box which can display or set any value,
numeric or otherwise.  The TextBox shows your desired
value when in Set mode, and the actual current value
when in Monitor mode.

The TextBox colours should change when you have entered
a desired value but not committed the change.  When the
change is committed, or the actual value coincides with
the desired value, then the colours will revert to normal.

You can configure the colours and font of a TextBox.
