// The module is largely intended to process video streams, except functionality
// provided by static functions which operate independent of previous frames. It
// is recommended, but not required that a unique instance be used for each
// concurrently processed stream. Similarly, it is recommended to call Reset()
// before switching to a new stream, but this is not absolutely required.
// The module provides basic thread safety by permitting only a single function
// to execute concurrently.
