    \brief
        Set the file-type identifier that will be used for future load
        operations.

        This allows us to pass the type on to Ogre when we process the image
        data (because it's just file data; we do not have a filename nor file
        extension).  Ogre needs this sometimes in order to correctly select the
        right codec to use for the final decoding of the data.  If this value
        is not set, loading may still succeed, though that will depend upon the
        specific libraries and codecs that the Ogre installation has available
        to it.

    \param type
        String object that describes the type of file data that will be passed
        in subsequent load operations.  Note that this type will typically be
        the file extension (or equivalent).
