sheaf 50d99e1e4b improve intervallic Bézier evaluation
Now we evaluate Bézier curves using an AABB computation. This results
in tighter intervals, which means that the cusp-finding algorithm
is better behaved.

sheaf 52420a1169 experiment: FMA backend for interval arithmetic
also includes the start of a way to observe which equations
are being solved, which should help with improving the performance of
the interval Newton method
