----- Method: ImageFormat>>printDescriptionOn: (in category 'printing') -----
+ The classic squeak image, aka V3, is 32-bit with magic 6502. The first 64-bit
+ Squeak image was generated from V3 image made by Dan Ingalls and Ian Piumarta
+ in 2005. Later, the magic code was changed to 68000.
+ After full closure support came to Squeak, the magic code changed to 6504 for
+ 32-bit and 68002 for 64-bit images by setting a capability bit.
+ Cog VM introduced a native order for floats under 6505 magic code. Its
+ corresponding 64b code would have been 68003 but no such image was produced.
+ Older Interpreter VMs would simply load 6505 by flipping word order back.
+ Cog VM also introduced a new object layout for 64-bit images called Spur layout
+ under a new magic code - 68021. A few images were also generated with 68019,
+ but this magic is now considered obsolete and deprecated.
