> Right now, a client replays part of the Filter locally by calling filterRowKey() and
filterAllRemaining() to determine whether it should continue to the next region.
> A number of new filters rely on filterKeyValue() and other calls to alter state.  It's
also a false assumption that all rows/keys affecting a filter returning true for FAR will
be seen client-side (what about those that failed the filter).
> This issue is about dealing with Filters properly from the client-side.
