+ *
+ * This is a thin algorithm that implements ScalerCrop for the RkISP2.
+ *
+ * As the cropping of the RkISP2 is controlled by parameter buffers instead of
+ * by V4L2 crop rectangles, it is more practical to implement the ScalerCrop
+ * control here instead of in the pipeline handler. This also has the positive
+ * side effect of supporting per-frame ScalerCrop.
