/**
 * Viewer components registry. Use this registry to register custom components.
 *
 * To implement custom component:
 *
 * 1. Define a component class implements {@link IComponent}.
 * 2. Define a constructor with a `viewer` parameter and add mouse event listeners for the specified viewer.
 * 3. Define the component logic in the event listeners. For example, listen for the `mousedown` event and
 *    select objects when the left mouse button is pressed.
 * 4. Override {@link IComponent.dispose} and remove mouse event listeners from the viewer.
 * 5. Register component provider in the components registry by calling the
 *    {@link components.registerComponent}.
 *
 * @example Implementing a custom component.
 *
 * ```javascript
 * import { IComponent, components, Viewer } from "@inweb/viewer-visualize";
 *
 * class MyComponent implements IComponent {
 *   protected viewer: Viewer;
 *
 *   constructor(viewer: Viewer) {
 *     this.viewer = viewer;
 *     this.viewer.addEventListener("mousedown", this.onMouseDown);
 *   }
 *
 *   override dispose() {
 *     this.viewer.removeEventListener("mousedown", this.onMouseDown);
 *   }
 *
 *   onMouseDown = (event: PointerEvent) => {
 *     // place custom logic here
 *   };
 * }
 *
 * components.registerComponent( "MyComponent", (viewer): IComponent => new MyComponent(viewer));
 * ```
