With the recording painter the actual painting operations are delayed, so now if multiple corner clippers are constructed, and they use a shared bitmap they can interfere with each other. The use of this shared bitmap was somewhat questionable anyway, so this is not much of a loss. This fixes the border-radius.html test page.
