 // 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.
