When Snap Alignment is turned on, dotted lines appear on the Stage when you drag an object to the specified snap
tolerance. For example, if you set Horizontal snap tolerance to 18 pixels (the default setting), a dotted line appears
along the edge of the object you are dragging when the object is exactly 18 pixels from another object. If you turn on
Horizontal Center Alignment, a dotted line appears along the horizontal center vertices of two objects when you
precisely align the vertices.
