+ * Android RAW sensor format:
+ *
+ * This format is exposed outside of the HAL to applications.
+ *
+ * RAW_SENSOR is a single-channel 16-bit format, typically representing raw
+ * Bayer-pattern images from an image sensor, with minimal processing.
+ *
+ * The exact pixel layout of the data in the buffer is sensor-dependent, and
+ * needs to be queried from the camera device.
+ *
+ * Generally, not all 16 bits are used; more common values are 10 or 12
+ * bits. All parameters to interpret the raw data (black and white points,
+ * color space, etc) must be queried from the camera device.
+ *
+ * This format assumes
+ * - an even width
+ * - an even height
+ * - a horizontal stride multiple of 16 pixels (32 bytes).
