* @type: FTC_FaceID
*
* @description:
* An opaque pointer type that is used to identity face objects.The
* contents of such objects is application-dependent.
*
* These pointers are typically used to point to a user-defined
* structure containing a font file path, and face index.
*
* @note:
* Never use NULL as a valid @FTC_FaceID.
*
* Face IDs are passed by the client to the cache manager that calls,
* when needed, the @FTC_Face_Requester to translate them into new
* @FT_Face objects.
*
* If the content of a given face ID changes at runtime, or if the value
* becomes invalid (e.g., when uninstalling a font), you should
* immediately call @FTC_Manager_RemoveFaceID before any other cache
* function.
*
* Failure to do so will result in incorrect behaviour or even
* memory leaks and crashes.
