charStroke()charStroke() changes the outline colour of any shapes drawn. Analagous to stroke() in p5. If col is a float between 0 and 1, it will use colourMapper() to determine the corresponding character. Otherwise if col is a character, it will outline shapes with that character directly. Beware notAllowedCharacters if using direct characters.
