About
This is a not yet finished collection of math utilities required to deal with polygons or so called arrangements consisting of 2D lines and bezier curves. It is still under heavy development and I do not suggest to use it in its current state.
Major difference to existing math libraries is a method to define the required precision of calculated results.
