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