Has anyone figured out the format of the Desktop DB file and how it could
be used by applications to access the icon data stored in Desktop DF?

In the olden days, the DesktopMgr init used a simple icon storage
technique.  The DesktopDF contains 512-byte records, each containing two
256-byte fields.  The first field is the b/w icon image, and the second
field is its mask.  Under System 7, the new DF format is more like a pile
of icons information, in no set order.  The DB file, obviously, includes
pointers into the DF file so that the Finder knows what a file's icon
should be when it draws out a folder window.

The DB file is a special tree format, I know.  But I can't glean much from
looking at its raw data.  Anyone else figured it out?
