28 * TODO:
29 * - I don't honor the maximum property set size.
30 * - Certain bogus files could result in reading past the end of a buffer.
31 * - Mac-generated files won't be read correctly, even if they're little
32 * endian, because I disregard whether the generator was a Mac. This means
33 * strings will probably be munged (as I don't understand Mac scripts.)
34 * - Not all PROPVARIANT types are supported.
35 * - User defined properties are not supported, see comment in
36 * PropertyStorage_ReadFromStream
