 // This is not in the FrameLoader class to emphasize that it does not depend on
 // private FrameLoader data, and to avoid increasing the number of public functions
 // with access to private data.  Since only this .cpp file needs it, making it
 // non-member lets us exclude it from the header file, thus keeping core/loader/FrameLoader.h's
