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 2b167f594a Make it easier to switch between 2 and 3-dim 
This commit makes it easier to switch between the 2-dim and 3-dim
formulations of the cusp-finding problem. This is still work in progress,
trying to improve the performance of the cusp-finding algorithms.

sheaf 0160081e80 Further modularisation of root isolation code 
The code is now generic over the dimension. There is a slight performance
loss that I need to investigate; perhaps some things are not getting
specialised? Maybe it is better to be more explicit about staging and
splice in the functions with fixed dimensions.
