Great! Of course, my next question is: Have you assured that your
algorithm returns `better' results? Have you compared with, say, a
floating point implementation which returns bboxes with really high
precisions? This page
http://processingjs.nihongoresources.com/bezierinfo/
has nice code for doing that, it seems.
