Unlike the legacy type, the radius isn't included in the bounds for the new curves type. This hasn't been obvious because the drawing is quite broken and doesn't use the radius properly. This commit adds a separate cache for the bounds with the radius, which is now used by default. The old cache is kept around for backward compatibility in the bounding box geometry node, where a new "Use Radius" option accesses the old behavior.
