[e-mod-tizen-screen-reader] Make opening QP easier by emiting events when touched upon
QP area.

For easier opening of QP, needs to emit mouse move events directly. Only
checking in horizontal direction is not enough, as second finger always out of QP
area. So, checking if y cordinate of fingers if lying in QP area in vertical
direction makes more sense.
