move non-HAL definitions to syste/core/include
This patch moves camera- and graphics-related definitions out of the hardware HAL layer and into system/core. These definitions are used both by the HAL and by higher-level code as well. More functionality (e.g., audio definitions) will be moved here as well. Change-Id: I225f12374ce54fa393640dce53738267d0d703e9 Signed-off-by: Iliyan Malchev <malchev@google.com>

/**
|

* 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.
