***NOTE:*** As of Dec.10 2010, this function has been renamed to OsGetTerrainHeight. Versions of OpenSimulator released after this date will give the user a deprecation warning, but for the time being will function as before. However, the deprecated function may eventually be removed entirely, and should therefore be avoided, and the new version be used instead.
