// This pipeline will drop all regular finished calls rather than
// passing them onto next. To finish downstream streams, call
// manualFinish. This makes it possible to pipe multiple streams
// (e.g. with QPDFObjectHandle::pipeStreamData) to a downstream like
// Pl_Flate that can't handle multiple calls to finish().
