I have been working on a Wikipedia article [0] for Haiku Vector Icon

as a Google Code-In task [1].
Looks pretty good!
Indeed.

Looks correct. One change I introduced in a later version is to use
multi-pass rendering in certain situations involving transparency in
styles. The previous single pass rendering is broken down into sequences
of single pass rendering until the next shape uses transparency
somewhere in it's style, which allows for certain compositing effects.

This is incorrect, Icon-O-Matic has its own native file format and IMSG
is the four byte magic value for those (icon BMessage archive). Little
endian 'ficn' (flat icon) is used for HVIF data. It should show up as
'ncif' in a hex editor, but I haven't made sure of this for the purpose
of this mail.
You could add a link to zuMi's icon site
http://zumi.xoom.it/myhaiku/system/index.html
for some examples. Maybe also to the user guide page on Icon-O-Matic
http://www.haiku-os.org/docs/userguide/en/applications/icon-o-matic.html,
as that would illustrate a bit the concepts of path, shape and style.
Those would be nice references indeed.
Best regards,
