[Devel] Small cache vs. Image cache

[Mike Owens]

I have a couple of questions concerning the cache manager.

1. Is there an advantage in using one cache verses the other? 
2. Is one faster than the other.
3. Are they designed to be used together or can they be used independently?
4. Do I have to manage what glyphs are assigned to what cache or does the cache 
system test for this in some way?
Thanks for your help
