/**
 * A component that provides resizing of shapes on the canvas.
 *
 * The following components are part of shape resize:
 *
 *  * adding resize handles,
 *  * creating a visual during resize
 *  * checking resize rules
 *  * committing a change once finished
 *
 *
 * ## Customizing
 *
 * It's possible to customize the resizing behaviour by intercepting 'resize.start'
 * and providing the following parameters through the 'context':
 *
 *   * minDimensions ({ width, height }): minimum shape dimensions
 *
 *   * childrenBoxPadding ({ left, top, bottom, right } || number):
 *     gap between the minimum bounding box and the container
 *
 * f.ex:
 *
 * ```javascript
 * eventBus.on('resize.start', 1500, function(event) {
 *   var context = event.context,
 *
 *  context.minDimensions = { width: 140, height: 120 };
 *
 *  // Passing general padding
 *  context.childrenBoxPadding = 30;
 *
 *  // Passing padding to a specific side
 *  context.childrenBoxPadding.left = 20;
 * });
 * ```
 *
