This is a proxy class for an asset. It contains an IASSET object. It is created
before the asset is loaded, and is involved in the loading. It implements
ILoadupProxy so that the Loadup utility can be used to manage the asset loading.
After loading is complete, this proxy remains as a repository of the IASSET object.
It is intended that this proxy can act for a range of asset types, providing there is
a suitable loader. As key to understanding the approach, see AssetTypeMapBase,
FlexAssetTypeMap, AssetFactory and AssetLoaderFactory.
The loader class, of type IAssetLoader, has a Delegate type role. It works for this
AssetProxy class and reports back to it.
