Method void QGraphicsGeoMap::setZoomLevel(qreal zoomLevel) doesn't accept non-integer values of zoomLevel

Method void QGraphicsGeoMap::setZoomLevel(qreal zoomLevel) doesn't accept non-integer values of zoomLevel. When I pass any fractional value in this method QGraphicsGeoMap draws garbage (black-white rectangles) instead of map image.

From our point of view when this method is called with fractional value as argument it should either round value inside itself, or (better) scale map image in order to support smooth zoom-in/out. As a result of this, user experience when doing zoom in/zoom out in Qt OVI maps is not so great - it's not smooth, but rather "jumps" when doing zooming.
