1. I'm not 100% all of these are usable when you take into consideration the
fact that SVG can have separate fill and stroke parameters, several types of
curved and/or boxy "line endings" (can't remember the correct term for
these...), and so on.

2. I've been considering instead using triangle meshes for everything, possibly
using one of the various parametric object approximation macros/tools people
have created over the years. It would make things a lot simpler since you could
just plug in the formulas and have the macros/tools take care of the rest. (In
fact, I think most software that renders SVG in real-time tends to operate in a
manner more similar to this technique.) Of course, the visual quality might be
inferior in several instances, but it is possible in most cases to tweak the
fidelity/granularity with which the objects and formulas are approximated and
replaced by meshes.

Some food for thought.
