d3f566ba54 Use complex numbers to implement points 
Shows a 30% speedup for me.

49c2d886a0 Use exact error 
To me, this looks about 40% faster.

WIP though.  API needs to change to take out error output argument.
Further optimization is possible by merging loops.

b568c934d0 Remove max_n parameter 
This is probably not useful as a parameter, so instead we hardcode the
value into the main module.

856ffe1fca Make only a few functions public 
This way we hopefully don't have to worry about changing things behind
the scenes.

4dffdb7dd7 cu2qu.__init__: return (spline[s], error[s]) tuple from curve[s]_to_quadratic; raise exception if no approximation is found; ensure returned spline is a list of tuples 2015-12-07 15:09:26 +00:00

561bed0ea0 Remove Point class and only use built-ins 
Using built-in types (mostly tuples) seems to cut the running time
overall by about one half. Spelling out linear interpolation in the
bezier_at functions actually cuts the running time by another 10%,
but I'm not sure if it's worth it given that this code looks a bit
nicer.

ebcd99b1df Rearrange some code 
Hopefully this should make the code supporting the public API more
clear.
