I think a subset of SVG would be fine for symbol definitions, as long as 
none of the key features/primitives are missing. I like the fact that 
this approach would add no dependencies, but OTOH we'd end up 
maintaining our own parser which sounds like a duplication of work when 
we could possibly delegate the parsing to an external library.

After further checking it seems that the libsvg-cairo option discussed 
earlier uses its own libsvg parser which has not been maintained since 
2005 either... so it's not a much better alternative than this agg/svg 
parser in the end.

Unfortunately I only know enough about SVG to be dangerous. Is there 
anyone familiar enough with the SVG spec that could give us an opinion 
from a quick browse of the 
agg-2.4/examples/svg_viewer/agg_svg_parser.cpp source file? Does this 
parser support enough of the SVG spec to be a viable solution?

Thanks in advance

Daniel
