Title: Fix to bug introduced by cache optimisations.

Unsure of the speed impact of this. Note that I make use of the ```vertices``` and ```codes``` of a matplotlib ```Path``` rather than using the suggested more public ```iter_segments()```. However, matplotlib does indicate that these internal numpy arrays can be treated as immutable.
