/**

* This object extends LuminanceSource around an array of YUV data returned from the camera driver,
|

* with the option to crop to a rectangle within the full data. This can be used to exclude
|
|
* superfluous pixels around the perimeter and speed up decoding.
|
|
*
|
|
* It works for any pixel format where the Y channel is planar and appears first, including
|
|
* YCbCr_420_SP and YCbCr_422_SP.
