/*
* Updown control
*
* Copyright 1997 Dimitrie O. Paun
*
* TODO:
* - I think I do not handle correctly the WS_BORDER style.
* (Should be fixed. <ekohl@abo.rhein-zeitung.de>)
*
* Testing:
* Not much. The following have not been tested at all:
* - horizontal arrows
* - listbox as buddy window
* - acceleration
* - base 16
* - integers with thousand separators.
* (fixed bugs. <noel@macadamian.com>)
*
* Even though the above list seems rather large, the control seems to
* behave very well so I am confident it does work in most (all) of the
* untested cases.
