 * @class   vtkCocoaMacOSXSDKCompatibility
 * @brief   Compatibility header
 *
 * VTK requires the Mac OS X 10.7 SDK or later.
 * However, this file is meant to allow us to use features from newer
 * SDKs by adding workarounds to still support the minimum SDK.
 * It is safe to include this header multiple times.
