There are some tools which generate SVG vectors more or less resembling 
a input raster image:
http://www.padc.mmpc.is.tsukuba.ac.jp/member/morik/fdssvg/
http://www.celinea.com/
and probably some more.
While the above work well for certain tasks, I sometimes would like to 
get single paths for lines, not a path around the edges of a line.

So if a line of 1 mm is scanned, and then traced, the "converter" or 
tracer could either
1. output one long closed path outlining the "line" (which is actually a 
colored area of non-zero width). That's what all tools I know of do.
2. (maybe as an option) find the path that's always in the middle of the 
line.

Does someone know of tools supporting the second option for line art?
I heard from an animator that some tool named "streamline" tries to do 
that, but generally fails.
