ZIM Bubbling: 102. hitTestPath - for ZIM at https://zimjs.com/
Check it out at https://zimjs.com/hittestpath.html.
We've added Squiggle and Blob addPoint(), addPoints() and interpolate() methods that have helped out making hit tests on paths possible with the new hitTestPath() method for all ZIM DisplayObject shapes. So this is very cool! It also is leading to dynamic bounds for Squiggle and Blobs so more on that later including dragging with Boundaries, etc.
