Factor in the percentage of the databuffer a BufferedMirage is using to

estimate its memory if its BufferedImage is a subimage of another
BufferedImage.

Include the amount of memory used by colorizations in ImageManager's cache
usage calculations.

Crank ImageManager's cache size up to 32 megs since a) it's actually seeing the
memory used by colorizations and b) the new seamonsters are pretty sizable.
