// when the current event is a mouse move (except when we are calling
// from _updateMouseoverWithEvent, so we have to use a global,

// right view. The global is forceNSViewHitTest and the method they use to
// do the hit testing is _hitViewForEvent:. (But this does not work correctly
// when there is HTML overlapping the view, see bug 4361626)
