Based on my testing during developing the caching stuff for Photo, it
appears that any change to the object adds a complete new copy of the
object.  When I just set _p_changed = 1, without even changing a property,
Data.fs increased by the size of the image plus a bit.

Of course, the ZC guys and probably others can verify this for sure.
