Configure the thumbnailer based on the thumbnail parameters given by the android request metadata. Only the thumbnail encoder needs to be configured, and since it is only used at post-processing time, move the configuration out of the post-processor constructor and into the processing step. Also set the following android result metadata tags: - ANDROID_JPEG_THUMBNAIL_SIZE - ANDROID_JPEG_THUMBNAIL_QUALITY Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
