    write new frames on top of an existing level.

    table be remapped, while frames on disk \a not in the table be
    \b deleted. Eventual frames present in the table but not on disk
    are ignored.
    \n\n
    The default implementation provides renumbering for standard
    Toonz multi-file level types (levelName.####c.ext), and does nothing
    if the specified path is not compatible with the multi-file format.
