I haven't started looking at this yet. Since I don't know or understand
the complex math is trying to guess at the best approximation, I had
planned to sample the two curve segments adjacent to the node in a
configureable number of places and send that list of points to the
bezier fitting functions in bezier-utils.cpp to have it find the best
fitting single segment approximation (I think that it has the ability to
do this with end tangent constraints). Does this sound like a reasonable
idea to the people in the know?
