/**
* <p>QuirkSummary
* Bug Id: 180819729
* Description: Quirk that should validate the video resolution of {@link CamcorderProfile}
* on legacy camera. When using the Camera 2 API in {@code LEGACY} mode (i.e.
* when {@link CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL} is set to
* {@link CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY}),
* {@link CamcorderProfile#hasProfile} may return {@code true} for unsupported
* resolutions. To ensure a given resolution is supported in LEGACY mode, the
* configuration given in
* {@link CameraCharacteristics#SCALER_STREAM_CONFIGURATION_MAP} must contain
* the resolution in the supported output sizes. The recommended way to check
* this is with {@link StreamConfigurationMap#getOutputSizes(Class)} with the
* class of the desired recording endpoint, and check that the desired
* resolution is contained in the list returned.
* Device(s): All legacy devices
* @see CamcorderProfile#hasProfile
* @see CamcorderProfileResolutionValidator
