When OOGL objetos are read from disk files, the OOGL library uses the file suffix to guess at the file type.
If the suffix is unrecognized, or if no suffix is available (e.g. for an objeto being read from a pipe, or embedded in another OOGL objeto), all known types of objetos are tried in turn until one accepts the data as valid.
