A Grapher view for Mastodon.

A new view in Mastodon, lets the user plot a feature as a function of another one in a XY plot.

Live demos:

The view is a standard Mastodon view, strongly inspired by TrackScheme. So it:

shares selection, highlight and focus with other views.
shares object coloring.
has styles.
has roughly the same navigation shortcuts (mouse navigation, zoom, etc. are made ike TrackScheme).
has Context support (though it is hacky compared to what TrackScheme has).
has some LOD (spot size changes depending on the proximity with other spots, like for TrackScheme).

Right now this must be considered a first version, to be perfected. Ideally we want:

a better renderer with better LOD, that exploits a KD-tree to avoid painting all the spots if the user requests.
to review the Context support.
make exporters to pdf and co.
add histograms.
