/**

*  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.
