It would be an easy enough algorithm to to
get all the vectors from the G-Code and
z-sort them to avoid islands. But we are
going to get back into the writing PC
software argument again if we do :D

I think the 24/32 wire EDM printer might
win in a race with a vector one at the end
of the day anyways.
