### [method:CompressedTexture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )

[page:String url] — the path or URL to the file. This can also be a [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].
[page:Function onLoad] (optional) — Will be called when load completes. The argument will be the loaded texture.
[page:Function onProgress] (optional) — Will be called while load progresses. The argument will be the ProgressEvent instance, which contains .[page:Boolean lengthComputable], .[page:Integer total] and .[page:Integer loaded]. If the server does not set the Content-Length header; .[page:Integer total] will be 0.
[page:Function onError] (optional) — Will be called when load errors.

Begin loading from url and pass the loaded texture to onLoad. The method also returns a new texture object which can directly be used for material creation.
