[BioC] Gviz DataTrack, type="densityplot"

[Hahne, Florian]

Hi Brent,
There is no particular reason why density plots are nor a standard plot
type in Gviz. I guess my reasoning was that those would not be necessary
because the only real application that I see here is for data smoothing,
and one can already archive that with the 'smooth' plot type. I am happy
to add this to the next release of Gviz. Thanks for the suggestion.
