> 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.
