 I could be missing something but I think the only real constraint is that
the first step must be done first. But you can associate the item index
with the item immediately when you're adding it to the list, not later.

 Yes.

 It's not a typical use of wxImageList, normally it contains a fixed number
of images while in your case, AFAIU, its contents is user-defined. So,
indeed, unusual precautions must be taken.

 What about calling SetImageList() with a dummy empty image list?
