/**
* Extent in two dimensions.
*
* Description
*
* This structure is used for component values that may be real numbers, represented with single-precision floating point. For representing extents in discrete values, such as texels, the integer variant {@link XrExtent2Di} is used instead.
*
* If used to represent physical distances, values must be in meters.
*
* The {@code width} and {@code height} value must be non-negative.
*
* See Also
*
* {@link XrCompositionLayerQuad}, {@link XrOffset2Df}, {@link XrPlaneDetectorLocationEXT}, {@link XrRect2Df}, {@link XrSceneMarkerMSFT}, {@link XrScenePlaneMSFT}, {@link VARJOMarkerTracking#xrGetMarkerSizeVARJO GetMarkerSizeVARJO}, {@link XR10#xrGetReferenceSpaceBoundsRect GetReferenceSpaceBoundsRect}
