The current system short circuits out when an SkTextBlob will draw anything based on its bounds, the bounds of the clip, and the state of the paint. A similar thing needs to happen, but the clip needs to be ignored. Return the nullptr if the SkTextBlob would never draw to signal that the Slug can be ignored.
