I should clarify a bit - creaturesImage /is/ a class. But I want to
override the /pointer/ serialization, rather than the class
serialization. As such, it doesn't matter if the representations of
the pointers are unchanged between two runs of the program; rather, it
matters that the class not be serialized by boost, as these classes
are rather heavy in terms of memory-mappings and other external
resources (hence using a global cache to share them).
