As in the original discussion, this is probably too fiddly and the
resulting SVG files are going to be really ugly anyway.  I think the
consensus was that we should use some toolchain that uses a source
format that looks like actual source code, such as the dot or xfig
formats, of stuff like that -- which is "compiled" into the target
graphic format.

As I recall, what we lacked was somebody with time and knowledge to
actually produce a useful image starting from such a source, produce
Makefile rules to run the transformation from the Makefiles, and to
inject the image into the SGML so that it works in the HTML and PDF
outputs.  With such a proof of concept we're much more likely to take
this idea seriously.
