The path Warp method allows the path to be transformed within a range (the four-point range); The first argument can be an array of 3 dots or 4 points, and if it is an array of 3, then the 4th point will automatically follow a parallelogram; The

The flatten method of the path can straighten the curve in the path until what extent it is determined by its second parameter (default 0.25); Its first argument is a matrix transformation, which means that flatten can perform matrix transformations
