# AutoScan --
# This procedure is invoked when the mouse leaves an entry window
# with button 1 down. It scrolls the window up, down, left, or
# right, depending on where the mouse left the window, and reschedules
# itself as an "after" command so that the window continues to scroll until
# the mouse moves back into the window or the mouse button is released.
#
# Arguments:
# w - The entry window.
# x - The x-coordinate of the mouse when it left the window.
# y - The y-coordinate of the mouse when it left the window.
