* MULTI-CHANNEL SIGNED DISTANCE FIELD GENERATOR
* ---------------------------------------------
* A utility by Viktor Chlumsky, (c) 2014 - 2023
*
* 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
