I was just playing around with this and what I've come up with so far is that
the Finder will create an entire IconFamily based upon the 'icl8' icon.  It
does this using the same algorithm as ResEdit does in its Family Icon Editor.
This means that the ICN# icon that is generated from your icl8 icon must
be completely enclosed in black bits.  So that when it is used to create the
mask, a solid mask is created.  Did that make sense?

The problem with the Hobbes icon is that it is not completely enclosed, so when
the mask is generated the black "paint" "leaks" out of the mask.  

One solution is to open up the file you are trying to change the icon of
using Resedit and hand patch the Icon Family rsrcs found therein.  I don't know
how to do this if you're trying to changed a Folder's Icon, because I don't
know how to get ResEdit to open a folder's rsrc fork.  Say, if a folder is
just a directory, where are the folder's Icons stored?  Hmmmm...

If you are trying to change a volume Icon, just change the Icon Family rsrcs
found in the invisible file "Icon" found on the root level of the volume.

P.S.  Does anyone else's copy of ResEdit 2.1 add an extra line to the Mask
icon when dragging one of the other family icons down to the mask rectangle?
Do I have a damaged copy??
