# tkScrlByUnits --
# This procedure tells the scrollbar's associated widget to scroll up
# or down by a given number of units.  It notifies the associated widget
# in different ways for old and new command syntaxes.
#
# Arguments:
# w -		The scrollbar widget.
# orient -	Which kinds of scrollbars this applies to:  "h" for
#		horizontal, "v" for vertical, "hv" for both.
# amount -	How many units to scroll:  typically 1 or -1.
