goog.userAgent.platform Namespace.VERSION {string}The version of the platform. We only determine the version for Windows and Mac, since it doesn't make much sense on Linux. For Windows, we only look at the NT version. Non-NT-based versions (e.g. 95, 98, etc.) are given version 0.0
.isVersion(version)Whether the user agent platform version is higher or the same as the given version.
