sheaf 1338d7ddbe Improve intervallic rotation computations 
This commit bakes in a certain kind of representation for brush strokes:

  c(t,s) = p(t) + R(theta(t)) b(t,s)

This representation allows us to cancel out some rotation terms when
computing the envelope equation, improving the efficiency of the
cusp-finding methods.

sheaf 96aa38b3c3 improve rotations in interval arithmetic 
Computing a rotation in interval arithmetic can lose tightness.
Instead of computing

   a cos phi + b sin phi

which doesn't account for the difference in phase in the two sinusoids,
it is better to use

  sqrt (a² + b²) * cos ( phi - atan2(a,b) )

which correctly estimates the maximum amplitude of the sum to be
sqrt(a²+b²) instead of abs(a) + abs(b).

This seems to worsen the performance of the interval Newton method
at the moment, possibly due to the complexity of the new formula,
which involves computing atan(b/a). Further investigation is needed.

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.

the interval Newton method
