- fixed 3137661 -- REGRESSION: autoscroll selection is broken

	The new logic in WebCore is slightly pickier, and can't abide a mouse-moved event
	coming in during a drag. Unfortunately, we were sending a fake mouse-moved event
	during a drag, so lets not do that.

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView mouseDown:]): Cancel any scheduled fake mouse-moved event.
        (-[WebHTMLView mouseUp:]): Send a fake mouse-moved event because we didn't update during the drag.

        * WebView.subproj/WebHTMLViewPrivate.m: (-[WebHTMLView _frameOrBoundsChanged]):
	Don't schedule a fake mouse-moved event if the mouse is down, because that means we are in the
        middle of a drag.
