/**
 * The GSplatComponent enables an {@link Entity} to render 3D Gaussian Splats. Splats are always
 * loaded from {@link Asset}s rather than being created programmatically. The asset type is
 * `gsplat` which are in the `.ply` file format.
 *
 * You should never need to use the GSplatComponent constructor directly. To add an
 * GSplatComponent to an {@link Entity}, use {@link Entity#addComponent}:
 *
 * ```javascript
 * const entity = pc.Entity();
 * entity.addComponent('gsplat', {
 *     asset: asset
 * });
 * ```
 *
 * Once the GSplatComponent is added to the entity, you can access it via the `gsplat` property:
 *
 * ```javascript
 * entity.gsplat.customAabb = new pc.BoundingBox(new pc.Vec3(), new pc.Vec3(10, 10, 10));
 *
 * console.log(entity.gsplat.customAabb);
 * ```
 *
 * Relevant Engine API examples:
 *
 * - [Loading a Splat](https://playcanvas.github.io/#/loaders/gsplat)
 * - [Custom Splat Shaders](https://playcanvas.github.io/#/loaders/gsplat-many)
