because it can't be C2 continuous after splitting (since I'm
doing uniform splines only, and the parametrization changes). So
just knock everything down to cubic Beziers.
Also draw lines to indicate angle and origin when Ctrl+dragging to
rotate in plane of screen.

loop), and open-ended splines, with their tangents specified at
their endpoints.
Also change constraint solver matrix size to 1024, on the theory
that a power of two will generate better array indexing, and
replace fabs() with my own function that for some reason is
faster.

a method that works on the piecewise linear segments, and then
refines any intersections that it finds by Newton's method. So now
I support cubics too, and circle-circle intersections, and the code
is much simpler.

tables from SolveSpace to their own class. This is intended to
simplify use of the constraint solver in a library.

or lines against lines. The constraints get rather screwed up
afterwards, of course.
So make arcs with the endpoints coincident into circles, instead
of nothings; since the first split of a circle produces that.
And don't warn after deleting just point-coincident or horiz/vert
constraints as a dependency; that's just a nuisance, because it
happens too often.
