/**
 * Konva wrapper around native 2d canvas context. It has almost the same API of 2d context with some additional functions.
 * With core Konva shapes you don't need to use this object. But you have to use it if you want to create
 * a custom shape or a custom hit regions.
 * @constructor
 * @memberof Konva
 * @example
 * const rect = new Konva.Shape({
 *    fill: 'red',
 *    width: 100,
 *    height: 100,
 *    sceneFunc: (ctx, shape) => {
 *      // ctx - is context wrapper
 *      // shape - is instance of Konva.Shape, so it equals to "rect" variable
 *      ctx.rect(0, 0, shape.getAttr('width'), shape.getAttr('height'));
 *
 *      // automatically fill shape from props and draw hit region
 *      ctx.fillStrokeShape(shape);
 *    }
 * })
