The right side of the graph represents the most recent time. Since
there is never anything interesting to the right of that, it makes
sense to have the origin of the scaling be there.
* grapher/Graph.hxx (getHorizontalScale): new function
* grapher/GraphStyle.cxx (GraphStyleBar::draw, GraphStyleDot::draw,
GraphStyleEvent::draw): Use cairo transform functions to set up
scaling.
(GraphStyleBar::dataIndexAtPoint, GraphStyleEvent::dataIndexAtPoint):
Base calculations on scaling from right.

I don't why I thought this ever worked.
* grapher/GraphStyle.cxx (GraphStyleEvent::dataIndexAtPoint): return
distance from beginning of buffer, not beginning of search bounds.

A silly change, but this works better with other tools, like git
diff. I should have started the C++ files this way.

* grapher/GraphStyle.cxx (GraphStyleEvent::draw): set event color in
inner loop.

* grapher/GraphStyle.cxx(GraphStyleEvent::dataIndexAtPoint,
GraphStyleBar::dataIndexAtPoint): check for empty graph data

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.

Start of code to be more selective about the association between the
hover text and the underling graph. Also, show the data set name in hover text.
* grapher/GraphStyle.hxx (dataIndexAtPoint): New virtual function.
* grapher/GraphStyle.cxx (dataIndexAtPoint): Implementation for bar graphs
* grapher/GraphWidget.cxx (onHoverTimeout): Use dataIndexAtPoint.

* grapher/Graph(draw): Move much drawing code to GraphStyle::draw
