I think this would likely correspond to the findDotsAtSegment helper method

https://github.com/adobe-webplatform/Snap.svg/blob/master/src/path.js#L1215

• Snap.path.findDotsAtSegment [ method ] **
  • Utility method **
  • Finds dot coordinates on the given cubic beziér curve at the given t
  • p1x (number) x of the first point of the curve
  • p1y (number) y of the first point of the curve
  • c1x (number) x of the first anchor of the curve
  • c1y (number) y of the first anchor of the curve
  • c2x (number) x of the second anchor of the curve
  • c2y (number) y of the second anchor of the curve
  • p2x (number) x of the second point of the curve
  • p2y (number) y of the second point of the curve
  • t (number) position on the curve (0..1) = (object) point information in format: o { o x: (number) x coordinate of the point, o y: (number) y coordinate of the point, o m: { o x: (number) x coordinate of the left anchor, o y: (number) y coordinate of the left anchor o }, o n: { o x: (number) x coordinate of the right anchor, o y: (number) y coordinate of the right anchor o }, o start: { o x: (number) x coordinate of the start of the curve, o y: (number) y coordinate of the start of the curve o }, o end: { o x: (number) x coordinate of the end of the curve, o y: (number) y coordinate of the end of the curve o }, o alpha: (number) angle of the curve derivative at the point o }
