/**
* Struct containing view projection state.
*
* Description
*
* The {@link XrView} structure contains view pose and projection state necessary to render a single projection view in the view configuration.
*
* Valid Usage (Implicit)
*
*
* - {@code type} must be {@link XR10#XR_TYPE_VIEW TYPE_VIEW}
* - {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
*
*
* See Also
*
* {@link XrFovf}, {@link XrPosef}, {@link XrViewLocateInfo}, {@link XrViewState}, {@link XR10#xrLocateViews LocateViews}
*
* Layout
