! \internal This slot is connected to the selection rect's \ref QCPSelectionRect::accepted signal when \ref setSelectionRectMode is set to \ref QCP::srmZoom. It determines which axis rect was the origin of the selection rect judging by the starting point of the selection, and then zooms the axes defined via \ref QCPAxisRect::setRangeZoomAxes to the provided \a rect (see \ref QCPAxisR
