Bezier implementation with instrumentation code.

For comparison you can see some screenshots of the Mozilla implementation in https://bugs.webkit.org/show_bug.cgi?id=94110

I have implemented the bezier version of this patch (find the attached patch). I did some benchmarks (the patch also includes the code used to get the data used in my analysis) and the bezier version is one order of magnitude slower than the non-bezier version. According to my results, the non-bezier version takes about 20 microseconds to draw while the bezier version takes about 220 microseconds. That is still fast in my oppinion.
