Updated scope: this patch now also implements parsing for object-view-box, not just the feature flag. Property accepts none | <basic-shape-rect> (inset(), rect(), and xywh()). All three forms are stored internally as InsetFunction in the computed style. The round <border-radius> variant of inset() and the rendering implementation are left for a follow up patch
