For an explanation of the various image formats, load package ImageFormat
from SqueakMap. Read the class comment first, then look at the class
side utility methods. Examples:

  ImageFormat versionDescriptions do: [:e | Transcript cr; show: e]

  (ImageFormat fromFile: Smalltalk imageName) description

Loosely speaking, Squeak 4.6 is image format 6405, and works with Cog
and interpreter VMs. Squeak 5.0 and trunk are image format 6521, and
work with Spur (32-bit).
