I can imagine how this can be a problem. Thin lines
than in your
original render have 1 pixel width, will be removed or suffer a strong
you
misunderstood. In the original SVG there are no thin lines. The thin
line was introduced/inserted by buggy down-rendering to the wanted size.
(There are coincident lines in the SVG).
antialias wen reduced down.
Re-rendering a image on a smaller resolution will result on a pixel
perfect image (except thick eyebrows), where 1 pixel width is still 1
pixel.
Also the double drawing would be mostly irrelvant, if first render to the
original given SVG size. It seems many problems are only introduced artifically
by this toughtless(?) rendering-philosophy of RSVG (or Imakemagic), IMHO. :-/
...and the situation is even more complex than that.
So more things
that thing can go wrong.
