Since Filter is a core-required module, we do not need to list it as a dependency in filter modules.  Technically, this is wrong (not listing a dependency).  I have not seen any filter module that actually lists filter as a requirement.  While it does not cause any serious problems, it does result in incomplete self-documentation.  Should we encourage filter module owners (including me) to correct this?
