/**
 * FileAttributes defines whole-SWF attributes. It is a place to put
 * information that belongs in the SWF header, but for which the SWF
 * header has no space.  FileAttributes must be the first tag in a SWF
 * file, or it will be ignored.
 * <p>
 * It is our hope that FileAttributes will be the only tag ever to
 * have this requirement of being located at a specific place in the
 * file.  (Otherwise, a complicated set of ordering rules could
 * ensue.)
 * <p>
 * Any information that applies to the whole SWF should hopefully be
 * incorporated into the FileAttributes tag.
