Subject: Hover text for event-style graphs

Don't draw the data value for an event; only display it in hover text.

* grapher/Graph.hxx (window2GraphCoords): new function
* grapher/Graph.cxx (window2GraphCoords): ditto
* grapher/GraphStyle.cxx (GraphStyleEvent::dataIndexAtPoint): new
  function implementation.
