Subject: grapher: remove _zoomFactor from horizontal scaling calculation

This makes zooming more consistent and less buggy.

* grapher/Graph.cxx (Graph::draw): Set graph time spread using
  _zoomFactor.
* grapher/Graph.hxx (Graph::getHorizontalScale): no _zoomFactor
* grapher/GraphWidget.cxx (on_motion_notify_event): Dragging increment
  uses _zoomFactor.
  (on_scroll_event): Set extents after changing the zoom factor with
  the scroll wheel.
