Bezier Spline Arc-Fitting Script

Start Date: 2014-08-01

A script, currently targeting QCAD, to convert a Bezier Spline exported from Illustrator into a Polyline containing line and arc segments.

There's actually no real reason for this since the approximation by tiny lines of splines is usually enough for a machine to work with, but theoretically conversion to a polyline with arc segments will allow for much less generated G-Code, and I am nothing if not theoretical.

Multitudinous maths coming soon.

Progress

Made a final push to get the script working. It now successfully produces a polyline through one iteration of arcfitting with no spline splitting. Some curves are approximated pretty well, but particularly eccentric ellipses become lozenges, which is not desirable.

Stubbed out guards (They all return false for now.) Figured at this point I should just convert it to coffeescript, which is morally and technically superior to javascript, and punt it over to github instead of dropbox.
