/**
* CAnimationDecoder
*
* Proxy for implementation of file based image class.
* @lib IHL.lib
* @since 3.0
*
* This class is a proxy for CAnimationDecoderWrapped
*
* We needed to wrap animation decoding in a proxy because sometimes the cache gets cleared when decoding
* is in progress; when that happens the animation gets deleted while it's in the middle (which causes all sorts
* of crashes and memory stomping). Now, the cache can delete the proxy while the animation is decoding; the proxy
* will pass on the delete request to the decoder which will cleanup (delete itself) when it's safe to do so.
