 // The basic usage of the Filter interface is described in the comment at
 // the beginning of filter.h. If Filter::Factory is passed a vector of
 // size greater than 1, that interface is implemented by a series of filters
 // connected in a chain. In such a case the first filter
 // in the chain proxies calls to ReadData() so that its return values
 // apply to the entire chain.
 //
 // In a filter chain, the data flows from first filter (held by the
 // caller) down the chain. When ReadData() is called on any filter
 // except for the last filter, it proxies the call down the chain,
 // filling in the input buffers of subsequent filters if needed (==
 // that filter's last_status() value is FILTER_NEED_MORE_DATA) and
 // available (== the current filter has data it can output). The last
 // Filter will then output data if possible, and return
 // FILTER_NEED_MORE_DATA if not. Because the indirection pushes
 // data along the filter chain at each level if it's available and the
 // next filter needs it, a return value of FILTER_NEED_MORE_DATA from the
 // final filter will apply to the entire chain.
