/** \brief Plug-in chunk header
 *
 *  \legacy To ensure compatibility with TDM/RTAS plug-ins whose implementation requires \c fSize to be equal
 *  to the size of the chunk's header plus its data, AAE performs some behind-the-scenes record keeping.
 *  <BR>
 *  <BR>
 *  The following actions are only taken for %AAX plug-ins, so, e.g., if a chunk is stored by an RTAS or TDM
 *  plug-in that reports data+header size in \c fSize and this chunk is then loaded by the %AAX version of the
 *  plug-in, the header size will be cached as-is from the legacy plug-in and will be subtracted out before
 *  the chunk data is passed to the %AAX plug-in.  If a chunk is stored by an %AAX plug-in and is then loaded
 *  by a legacy plug-in, the legacy plug-in will receive the cached plug-in header with \c fSize equal to the
 *  data+header size.
 *  <BR>
 *  <BR>
 *  These are the special actions that AAE takes to ensure backwards-compatibility when handling %AAX chunk data:
 *  - When AAE retrieves the size of a chunk from an %AAX plug-in using
 *    \ref AAX_IACFEffectParameters::GetChunkSize() "GetChunkSize()", it adds the chunk header size to the
 *    amount of memory that it allocates for the chunk <BR>
 *  - When AAE retrieves a chunk from an %AAX plug-in using \ref AAX_IACFEffectParameters::GetChunk() "GetChunk()",
 *    it adds the chunk header size to \c fChunkSize before caching the chunk <BR>
 *  - Before calling \ref AAX_IACFEffectParameters::SetChunk() "SetChunk()" or
 *    \ref AAX_IACFEffectParameters::CompareActiveChunk() "CompareActiveChunk()", AAE subtracts the chunk header
 *    size from the cached chunk's header's \c fChunkSize member
