# Increment --
# This procedure is invoked to increment the value of a scale and
# to set up auto-repeating of the action if that is desired. The
# way the value is incremented depends on the "dir" and "big"
# arguments.
#
# Arguments:
# w - The scale widget.
# dir - "up" means move value towards -from, "down" means
# move towards -to.
# big - Size of increments: "big" or "little".
# repeat - Whether and how to auto-repeat the action: "noRepeat"
# means don't auto-repeat, "initial" means this is the
# first action in an auto-repeat sequence, and "again"
# means this is the second repetition or later.
