# tkScrollSelect --
# This procedure is invoked when button 1 is pressed over the scrollbar.
# It invokes one of several scrolling actions depending on where in
# the scrollbar the button was pressed.
#
# Arguments:
# w -           The scrollbar widget.
# element -     The element of the scrollbar that was selected, such
#               as "arrow1" or "trough2".  Shouldn't be "slider".
# 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.
