One thing that may not be obvious about IKIcon is how I envision a
theme switch to happen, so I thought I'd elaborate that here in case
you see any flaws and so it's recorded somewhere when it comes time
to implement this.
Basically, every IKIcon that is a standard icon knows its icon
identifier, and thus knows how to reload its icon image from the
corresponding image file from the current theme. To do this, you use
the -update method.
Every composited icon, OTOH, will eventually carry a pointer to the
two IKIcon objects it is based on around. That way, when the theme is
changed and e.g. the folder icon changes, all IKIcons that are badged
folders can register for the icon updated notification of the icon
they're based on and re-composite themselves with the updated icons.
So, whenever a theme switch happens, all the icon provider will have
to do is call "update" on the icon cache, and all icons on the
display should upgrade automatically. Of course, anyone who held on
to the NSImage won't get the update, but those using the IKIcon at
least will.
