+ * MULTI-CHANNEL SIGNED DISTANCE FIELD GENERATOR v1.9 (2021-05-28)
+ * ---------------------------------------------------------------
+ * A utility by Viktor Chlumsky, (c) 2014 - 2021
+ *
+ * The technique used to generate multi-channel distance fields in this code
+ * has been developed by Viktor Chlumsky in 2014 for his master's thesis,
+ * "Shape Decomposition for Multi-Channel Distance Fields". It provides improved
+ * quality of sharp corners in glyphs and other 2D shapes compared to monochrome
+ * distance fields. To reconstruct an image of the shape, apply the median of three
+ * operation on the triplet of sampled signed distance values.
