 * When calling JAWT_GetAWT with a JAWT version less than 1.7, you must pass this
 * flag or you will not be able to get a valid drawing surface and JAWT_GetAWT will
 * return false. This is to maintain compatibility with applications that used the
 * interface with Java 6 which had multiple rendering models. This flag is not necessary
 * when JAWT version 1.7 or greater is used as this is the only supported rendering mode.
 *
 * Example:
 *   JAWT awt;
 *   awt.version = JAWT_VERSION_1_4 | JAWT_MACOSX_USE_CALAYER;
 *   jboolean success = JAWT_GetAWT(env, &awt);

 * JAWT_DrawingSurfaceInfo->platformInfo points to a NSObject that conforms to the
 * JAWT_SurfaceLayers protocol. Setting the layer property of this object will cause the
 * specified layer to be overlaid on the Components rectangle. If the window the
 * Component belongs to has a CALayer attached to it, this layer will be accessible via
 * the windowLayer property.
