# 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.
