* Fillet/chamfer: point the drag arrow into the corner on inside edges (#1384) The radius/distance arrow always pointed against the faces' outward bisector, which is into the body on an outside edge but away from the corner on an inside one, where the blend adds material. The arrow and the spline radius handles now take each edge's convexity into account, so dragging out along the arrow grows the value on both kinds of edge, and each edge of a mixed chain follows its own.
