Stressing our rendering infrastructure with some more demanding content was another motivation when I started to work on SVG, so I think I can declare success here.
The N-closest or N-best dithering algorithm is a straightforward solution to the N-candidate problem.

This is essentially the inverse distance weighting (IDW) method for multivariate interpolation, also known as Shepard’s method. The following pseudocode sketches out a possible implementation:，更多细节参见91视频
