Subject: marshal_load, marshal_dump

Currently RMagick uses the old _dump and _load methods to 
marshal/unmarshal images. I'd like to start using the new marshal_load 
and marshal_dump methods. What is the impact of switching? Can I just 
replace _dump and _load with marshal_dump and marshal_load? Suppose I 
have an image that was dumped using an old version of RMagick. How do I 
support loading it?
