Lists of formats supported by the input and output filters respectively.
These lists are used for negotiating the format to actually be used, which will be loaded into the format member, above, when chosen.

The picture reference currently being sent across the link by the source filter.
This is used internally by the filter system to allow automatic copying of pictures which do not have sufficient permissions for the destination. This should not be accessed directly by the filters.
