Thanks for the further tips! I'll look at the R Internals manual,
the other built-in devices, and the RSvgDevice package. And I'm
still looking for the S source code, but I have a feeling that I'll
wind up writing the device before I find the source code.

While this would be a good idea for pretty much any other file format,
it probably will make things more complicated for HPGL as the structure
of base R graphics is kind of exactly the same as HPGL.
