System property for facial tracking.

Description

An application can inspect whether the system is capable of two of the facial tracking by extending the XrSystemProperties with XrSystemFacialTrackingPropertiesHTC structure when calling GetSystemProperties.

Valid Usage (Implicit)

The XR_HTC_facial_tracking extension must be enabled prior to using XrSystemFacialTrackingPropertiesHTC
type must be TYPE_SYSTEM_FACIAL_TRACKING_PROPERTIES_HTC
next must be NULL or a valid pointer to the next structure in a structure chain

If a runtime returns FALSE for supportEyeFacialTracking, the runtime must return ERROR_FEATURE_UNSUPPORTED from CreateFacialTrackerHTC with FACIAL_TRACKING_TYPE_EYE_DEFAULT_HTC set for XrFacialTrackingTypeHTC in XrFacialTrackerCreateInfoHTC. Similarly, if a runtime returns FALSE for supportLipFacialTracking the runtime must return ERROR_FEATURE_UNSUPPORTED from CreateFacialTrackerHTC with FACIAL_TRACKING_TYPE_LIP_DEFAULT_HTC set for XrFacialTrackingTypeHTC in XrFacialTrackerCreateInfoHTC.

    XrStructureType type;
