Section 4.4 of Mebarki et al "Farthest point seeding for placement of
streamlines" (INRIA No 5524, March 2005) notes "Our algorithm can take as 
input
a non uniform density field, or simply evaluate any function of the flow such
as velocity or vorticity". Fig.8 in the above shows streamlines placed
according to velocity. 

The CGAL manual (section 53.3) also briefly mentions density as an input, but
does not tell how to make it a function of the flow.

I would like to plot streamlines of my data with density proportional to
velocity, but I don't see how to provide this input to Stream_lines_2.
Suggestions appreciated.
