Cairo falls back to rasterisation as soon as it encounters anything
which it might not be able to implement using vector operations.

For me, a simple "d.vect fields" produces "real" (vector) SVG output.
You might want to experiment with the command options (and the
environment variables used by the cairo driver) to see if a specific
feature is triggering rasterisation.
