713 released, EEventKeyUp is generated.
714 However, it is possible that only the EEventKey is generated alone, typically
715 in relation to virtual keyboards. In that case we need to take care to
716 generate both press and release events in Qt, since applications expect that.
717 We do this by having three states for each used scan code, depending on the
