* Phaser - Display - DynamicTexture

* Game Objects can be assigned a DynamicTexture, so when they render in the world they do so
|
|
* based on the contents of the texture at the time. This allows you to create powerful effects
|
|
* once and have them replicated across as many game objects as you like.
