shader(key, url, overwrite) → {Phaser.Loader}
Adds a fragment shader file to the current load queue.
The file is not loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.
The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.
Retrieve the file via Cache.getShader(key).
The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.
If the URL isn't specified the Loader will take the key and create a filename from that. For example if the key is "blur"
and no URL is given then the Loader will set the URL to be "blur.frag". It will always add .frag as the extension.
If you do not desire this action then provide a URL.
