* 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. The camera instance then periodically
* sends the message CAMERA_MSG_PREVIEW_FRAME (if enabled) each time
* a new preview frame is available. If data callback code needs to use
* this memory after returning, it must copy the data.
*
* Prior to taking a picture, CameraService calls autofocus(). When auto
* focusing has completed, the camera instance sends a CAMERA_MSG_FOCUS notification,
* which informs the application whether focusing was successful. The camera instance
* only sends this message 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. At this point, if a shutter, postview, raw, and/or compressed callback
* is desired, the corresponding message must be enabled. As with CAMERA_MSG_PREVIEW_FRAME,
* any memory provided in a data callback must be copied if it's needed after returning.
