/**
* @classdesc
* Experimental
* A Plane Game Object.
*
* The Plane Game Object is a helper class that takes the Mesh Game Object and extends it,
* allowing for fast and easy creation of Planes. A Plane is a one-sided grid of cells,
* where you specify the number of cells in each dimension. The Plane can have a texture
* that is either repeated (tiled) across each cell, or applied to the full Plane.
*
* The Plane can then be manipulated in 3D space, with rotation across all 3 axis.
*
* This allows you to create effects not possible with regular Sprites, such as perspective
* distortion. You can also adjust the vertices on a per-vertex basis. Plane data becomes
* part of the WebGL batch, just like standard Sprites, so doesn't introduce any additional
* shader overhead. Because the Plane just generates vertices into the WebGL batch, like any
* other Sprite, you can use all of the common Game Object components on a Plane too,
* such as a custom pipeline, mask, blend mode or texture.
*
* You can use the `uvScroll` and `uvScale` methods to adjust the placement and scaling
* of the texture if this Plane is using a single texture, and not a frame from a texture
* atlas or sprite sheet.
*
* The Plane Game Object also has the Animation component, allowing you to play animations
* across the Plane just as you would with a Sprite.
*
* While a Plane cannot be enabled for input it does have the methods `hasFaceAt` and
* `getFaceAt` which can be used with Pointer coordinates to detect if they have clicked
* on Plane face, or not.
*
* Note that the Plane object is WebGL only and does not have a Canvas counterpart.
*
* The Plane origin is always 0.5 x 0.5 and cannot be changed.

* frameRate: 15,

*

* you can call the `Animation.create` method instead. It accepts the exact same parameters as when
* creating a global animation, however the resulting data is kept locally in this Plane.
*
* With the animation created, either globally or locally, you can now play it on this Plane:
*
* ```javascript
* const plane = this.add.plane(...);
* plane.play('run');
* ```
*
* Alternatively, if you wish to run it at a different frame rate for example, you can pass a config
* object instead:
*
* ```javascript
* const plane = this.add.plane(...);
* plane.play({ key: 'run', frameRate: 24 });
* ```
*
* When playing an animation on a Plane it will first check to see if it can find a matching key
* locally within the Plane. If it can, it will play the local animation. If not, it will then
* search the global Animation Manager and look for it there.
*
* If you need a Plane to be able to play both local and global animations, make sure they don't
* have conflicting keys.
