I've been looking for ages for some code to convert Cubic Bezier to Quadratic. I've only found some code on OpenSWF but is incomplete in some point (most methods in the CDoublePoint class like WhichSide or Intersection) are undocumented and not obvious. Another implementation is in the Ming library but doesn't work in most cases. I've found some explanation in cryptic mathematical language in some other site, but apparently nobody else care about this problem. My question: is it possible that nobody can point me out to some working code? (Language doesn't really matter).

Thanx in advance,
Lev
