Fix zooming when presenter dimensions are not integers...

Fix zooming when presenter dimensions are not integers If presenter width (or height) is not an integer, zooming using vertical (or horizontal) rubberband will cause the fixed dimension to change, because rubberband uses QRect instead of QRectF. Fixed by forcing the corresponding plotArea dimension for the fixed rubberband dimension when calling zoomIn() in mouseReleaseEvent. Task-number: QTRD-1905 Reviewed-by: Mika Salmela
