Chunk Information

[This is preliminary documentation and subject to change.]

Because the IFilter implementation needs to store some chunk information when operations other than content indexing occur, the following flag has been added to allow IFilter to be optimized for the indexing situation:

IFILTER_INIT_INDEXING_ONLY

The client only calls IFilter::Init once. The client does not use the function BindRegion eliminating the possibility of accessing a chunk both before and after accessing another chunk.
