//
// The conversion is by performing the hit test. Note that e.LocationInWindow is NOT
// updated by the time the tracking events are received and thus e.Window.
// MouseLocationOutsideOfEventStream has to be used instead.
//
// The Exited event has to be handled the same way as the entered event to cover the
// following scenario:
// ___________________________
// | Panel |
// | ______________ |
// | | Button | |
//
// When you move the mouse over the Button you will receive the Entered event for
// it. At the same time the Panel already had Entered called for its own tracking area.
// Now moving the mouse away from the Button into the Panel area will cause an
// Exited event on the Button's tracking rectangle, but it will NOT generate any
// Entered event. In the System.Windows.Forms world we want to receive WM_MOUSELEAVE
// on the Button and WM_MOUSE_ENTERED on the Panel.
