kute.js/src/components/svgDrawBase.js
thednp 2a5bac2bb3 Changes V2.2.0:
* major JSDoc write up
* removed ESLint `no-bitwise` exception, it only applies to specific functions and not the entire code
* the `SVGCubicMorph` component will remove un-necessary `Z` path commands when is the case for better out of the box animation
* fixed a minor disambiguation with `filterEffects` and `drop-shadow` property and its `dropshadow` interpolation function
* TypeScript strong: all files are modules, easy to implement in any third party app
* updated `CubicBezier` and SVGPathCommander
* code cleanup
