* Android RAW10 format:
*
* This format is exposed outside of the camera HAL to applications.
*
* RAW10 is a single-channel, 10-bit per pixel, densely packed, unprocessed
* format, representing raw Bayer-pattern images coming from an image sensor.
*
* In an image buffer with this format, starting from the first pixel, each 4
* consecutive pixels are packed into 5 bytes (40 bits). Each one of the first
* 4 bytes contains the top 8 bits of each pixel, The fifth byte contains the
* 2 least significant bits of the 4 pixels, the exact layout data for each 4
* consecutive pixels is illustrated below (Pi[j] stands for the jth bit of
* the ith pixel):
*
* bit 7 bit 0
* =====|=====|=====|=====|=====|=====|=====|=====|
* Byte 0: |P0[9]|P0[8]|P0[7]|P0[6]|P0[5]|P0[4]|P0[3]|P0[2]|
* |-----|-----|-----|-----|-----|-----|-----|-----|
* Byte 1: |P1[9]|P1[8]|P1[7]|P1[6]|P1[5]|P1[4]|P1[3]|P1[2]|
* |-----|-----|-----|-----|-----|-----|-----|-----|
* Byte 2: |P2[9]|P2[8]|P2[7]|P2[6]|P2[5]|P2[4]|P2[3]|P2[2]|
* |-----|-----|-----|-----|-----|-----|-----|-----|
* Byte 3: |P3[9]|P3[8]|P3[7]|P3[6]|P3[5]|P3[4]|P3[3]|P3[2]|
* |-----|-----|-----|-----|-----|-----|-----|-----|
* Byte 4: |P3[1]|P3[0]|P2[1]|P2[0]|P1[1]|P1[0]|P0[1]|P0[0]|
* ===============================================
*
* This format assumes
* - a width multiple of 4 pixels
* - an even height
* - a horizontal stride equal to the width
* - a vertical stride equal to the height
* - strides are specified in pixels, not in bytes
*
* size = stride * height * 10 / 8
*
* This format must be accepted by the gralloc module when used with the
* following usage flags:
* - GRALLOC_USAGE_HW_CAMERA_*
* - GRALLOC_USAGE_SW_*
* - GRALLOC_USAGE_RENDERSCRIPT
