+ *  rather than giving libdcp all the frames in one go).
+ *
+ *  Objects of this class can only be created with StereoPictureAsset::start_write().
+ *
+ *  Frames can be written to the MonoPictureAsset by calling write() with a JPEG2000 image
+ *  (a verbatim .j2c file).  finalize() must be called after the last frame has been written.
+ *  The action of finalize() can't be done in MonoPictureAssetWriter's destructor as it may
+ *  throw an exception.
