Toolkit does not do any caching of the images. If you request two copies
of the same image (eg by URL) it will fetch and create new instances
each time. You need to implement your own caching scheme. I suggest you
make heavy use of weak references when you do this in order to avoid
blowing out memory usage.

Can't answer this. My, now faulty, memory suggests that it didn't. If it
did, it was not kept between successive calls to load() or multiple
instances (for example inlined geometry didn't use the same instance).
However, I will stand corrected if that is not the case.
