/**
 * <p>QuirkSummary
 *     Bug Id: b/123897971
 *     Description: Quirk required to turn on/off HDR+ on Pixel devices by enabling/disabling
 *                  zero-shutter-lag (ZSL) mode on the capture request, depending on the image
 *                  capture use case's capture mode, i.e. prioritizing image capture latency over
 *                  quality, or vice versa. This means that when the capture mode is
 *                  {@link ImageCapture#CAPTURE_MODE_MINIMIZE_LATENCY}, HDR+ is turned off by
 *                  disabling ZSL, and when it is
 *                  {@link ImageCapture#CAPTURE_MODE_MAXIMIZE_QUALITY}, HDR+ is turned on by
 *                  enabling ZSL.
 *     Device(s): Pixel 2, Pixel 2 XL, Pixel 3, Pixel 3 XL
