Simpler, yes, but not substantially so.  I would prefer to keep both blocky
and corner-cutting algorithms together so that there is only one extension
to maintain when we eventually remove the old code.

That is certainly desirable, but not part of the work I am doing.  I am
rewriting the C/C++ code that calculates the contours, but the interface
between that and the python contour code remains the same, apart from some
trivial changes of course.
