------- Additional Comments from Viet-Trung Luu <viettrungluu at gmail.com>
EventHandler::m_lastScrollbarUnderMouse is currently only updated on mouse move
and not on mouse down, which makes it fail (or at least behave oddly) when a
mouse down on a scrollbar occurs without a mouse move onto the scrollbar; this
patch fixes this.
