If your bounds are not being recomputed, then you are missing a call to 
Modified() somewhere - most likely down in your point data. Some of the set 
methods are "fast' in that they don't check bounds and they don't call 
Modified() - assuming that you will do this once at the end when you are 
done with your modifications.
