/* Memory object destruction
 *
 * Apple extension for use to manage externally allocated buffers used with cl_mem objects with CL_MEM_USE_HOST_PTR
 *
 * Registers a user callback function that will be called when the memory object is deleted and its resources 
 * freed. Each call to clSetMemObjectCallbackFn registers the specified user callback function on a callback 
 * stack associated with memobj. The registered user callback functions are called in the reverse order in 
 * which they were registered. The user callback functions are called and then the memory object is deleted 
 * and its resources freed. This provides a mechanism for the application (and libraries) using memobj to be 
 * notified when the memory referenced by host_ptr, specified when the memory object is created and used as 
 * the storage bits for the memory object, can be reused or freed.
 *
 * The application may not call CL api's with the cl_mem object passed to the pfn_notify.
 *
 * Please check for the "cl_APPLE_SetMemObjectDestructor" extension using clGetDeviceInfo(CL_DEVICE_EXTENSIONS)
 * before using.

 *
 * This extension allows a 2D image to be created from a cl_mem buffer without a copy.
 * The type associated with a 2D image created from a buffer in an OpenCL program is image2d_t.
 * Both the sampler and sampler-less read_image built-in functions are supported for 2D images
 * and 2D images created from a buffer.  Similarly, the write_image built-ins are also supported
 * for 2D images created from a buffer.
 *
 * When the 2D image from buffer is created, the client must specify the width,
 * height, image format (i.e. channel order and channel data type) and optionally the row pitch
 *
 * The pitch specified must be a multiple of CL_DEVICE_IMAGE_PITCH_ALIGNMENT pixels.
 * The base address of the buffer must be aligned to CL_DEVICE_IMAGE_BASE_ADDRESS_ALIGNMENT pixels.
