  24 /* Bezier curve rasterizer.
  25  *
  26  * De Casteljau Bezier rasterizer is faster, but currently rasterizing curves with cusps sligtly wrong.
  27  * It doesn't really matter in practice.
  28  *
  29  * AFD tesselator is somewhat slower, but does cusps better.
  30  *
  31  * McSeem rasterizer should have the best quality, bit it is the slowest method. Basically, you will
  32  * never notice any visial difference. But it can render something... ahem... sensible with very low
  33  * recursion levels (as low as 1), while standard De Casteljau produces garbage if its built-in
  34  * "flatness limit" is not reached. so McSeem tesselator is the default here.
  35  * On Baphomet test It is slower than De Casteljau by about 100 *micro*seconds. I'm ok with that.
