This fixes something that I felt was off for a while. Previously, when
you'd click on the titlebar to move the window, the titlebar would only
change its background once the moving starts, but not on mouse-down.
That felt really off, since the moving is down with mouse-down and move,
so I think giving the user feedback about the mouse-down event makes
more sense.
I know there's a subjectivity to this change, so I'm ready to hear other
opinions, but for now I want to go with this.
