Detailed Description
A helper class for writing to MonoPictureAssets.
Objects of this class can only be created with MonoPictureAsset::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.
