LDView actually has experimental support for this built-in (although it has to
be manually enabled via either a command line switch or a registry setting).
Unfortunately, it's effectively useless on anything other than individual parts
due to the astronomically large output files, and their extremely slow
processing. The results also tend to not render nicely in most SVG renderers
(particularly transparent parts). See below for the output from car.dat
(WARNING: 8.3MB file).

Here's a single part (276KB):

The above also has another experimental LDView feature (OBI: Old/Original
Building Instructions) enabled with a custom part file to make use of that
feature. That's why the sides of many of the cylinders are black.
