+ * A set of bit masks for specifying how the received preview frames are
+ * handled before the previewCallback() call.
+ *
+ * The least significant 3 bits of an "int" value are used for this purpose:
+ *
+ * ..... 0 0 0
+ *       ^ ^ ^
+ *       | | |---------> determine whether the callback is enabled or not
+ *       | |-----------> determine whether the callback is one-shot or not
+ *       |-------------> determine whether the frame is copied out or not
+ *
+ * WARNING:
+ * When a frame is sent directly without copying, it is the frame receiver's
+ * responsiblity to make sure that the frame data won't get corrupted by
+ * subsequent preview frames filled by the camera. This flag is recommended
+ * only when copying out data brings significant performance price and the
+ * handling/processing of the received frame data is always faster than
+ * the preview frame rate so that data corruption won't occur.
+ *
+ * For instance,
+ * 1. 0x00 disables the callback. In this case, copy out and one shot bits
+ *    are ignored.
+ * 2. 0x01 enables a callback without copying out the received frames. A
+ *    typical use case is the Camcorder application to avoid making costly
+ *    frame copies.
+ * 3. 0x05 is enabling a callback with frame copied out repeatedly. A typical
+ *    use case is the Camera application.
+ * 4. 0x07 is enabling a callback with frame copied out only once. A typical use
+ *    case is the Barcode scanner application.

+ * CameraHardwareInterface.h defines the interface to the
+ * camera hardware abstraction layer, used for setting and getting
+ * parameters, live previewing, and taking pictures.
+ *
+ * It is a referenced counted interface with RefBase as its base class.
+ * CameraService calls openCameraHardware() to retrieve a strong pointer to the
+ * instance of this interface and may be called multiple times. The
+ * following steps describe a typical sequence:
+ *
+ *   -# After CameraService calls openCameraHardware(), getParameters() and
+ *      setParameters() are used to initialize the camera instance.
+ *      CameraService calls getPreviewHeap() to establish access to the
+ *      preview heap so it can be registered with SurfaceFlinger for
+ *      efficient display updating while in preview mode.
+ *   -# startPreview() is called, which is passed a preview_callback()
+ *      function and a user parameter. The camera instance then periodically
+ *      calls preview_callback() each time a new preview frame is available.
+ *      The callback routine has two parameters: the first is a pointer to
+ *      the IMemory containing the frame and the second a user parameter. If
+ *      the preview_callback code needs to use this memory after returning,
+ *      it must copy the data.
+ *
+ * Prior to taking a picture, CameraService calls autofocus() with
+ * autofocus_callback() and a user parameter. When auto focusing has
+ * completed, the camera instance calls autofocus_callback(), which informs
+ * the application whether focusing was successful. The camera instance
+ * only calls autofocus_callback() once and it is up to the application to
+ * call autoFocus() again if refocusing is desired.
+ *
+ * CameraService calls takePicture() to request the camera instance take a
+ * picture. This method has two callbacks: raw_callback() and jpeg_callback().
+ * When the raw image is available, raw_callback() is called with a pointer
+ * to the IMemory containing the raw image. When the jpeg image is available,
+ * jpeg_callback() is called with a pointer to the IMemory containing the
+ * jpeg image. As with preview_callback(), the memory must be copied if it's
+ * needed after returning.
