Looks like an interesting project...
I don't think there's any way to add extra data *inside* an HVIF
structure, but do you really need to? You surely can just create an item
that holds both the HVIF data and your own additions.
Not sure how your "nodes" would be stored (and how the icons are to
be read and displayed) but if they're files I'd have thought you could
just attach an icon. If you're going to display them in your own window
(which I assume you have to), you'll need to decode and display the HVIF
yourself anyway.
I do something similar in my "MusicWeaver" app -- although I'm still
using bitmap icons [too many to do over at the moment...!]. Each module
is actually an add-on, so it's a *lot* more than an icon, but the icon
image is in the resource section so the Tracker gets it automatically.
When I place the item in a diagram window, I draw the image myself.
I don't have user-generated images, but you should be able to have some
way to drop an Icon file into your app to insert it into a node.
