/**

* @classdesc
|
|
* The Pipeline Manager is responsible for the creation, activation, running and destruction
|
|
* of WebGL Pipelines in Phaser 3.
|
|
*
|
|
* The `WebGLRenderer` owns a single instance of the Pipeline Manager, which you can access
|
|
* via the `WebGLRenderer.pipelines` property.
|
|
*
|
|
* By default, there are 5 pipelines installed into the Pipeline Manager when Phaser boots:
|
|
*
|
|
* 1. The Multi Pipeline. Responsible for all multi-texture rendering, i.e. Sprites, Shapes.
|
|
* 2. The Single Pipeline. Responsible for rendering Game Objects that explicitly require one bound texture.
|
|
* 3. The Rope Pipeline. Responsible for rendering the Rope Game Object.
|
|
* 4. The Light Pipeline. Responsible for rendering the Light Game Object.
|
|
* 5. The Bitmap Mask Pipeline. Responsible for Bitmap Mask rendering.
|
|
*
|
|
* You can add your own custom pipeline via the `PipelineManager.add` method. Pipelines are
|
|
* identified by unique string-based keys.
