The ::edge-reached signal is emitted whenever user-initiated scrolling
makes the scrolledwindow exactly reaches the lower or upper limits
defined by the adjustment in that orientation.
A similar behavior with edge resistance is provided by the
#GtkScrolledWindow::edge-overshot signal.
Note: The @pos argument is LTR/RTL aware, so callers should be aware too
if intending to provide behavior on horizontal edges.
