BndBox for Geom_Line. In the algorithm of the point search on the segment, a projection is built. In case of Geom_Line it is built on the infinite line. So, we need to check the point if it is in the box.
Drag&drop correction to don't show selection bounding rect. To restore selection after drag operation.
