 // To store a multi-selection, in your application you could:
 // - A) Use this helper as a convenience. We use our simple key->value ImGuiStorage as a std::set<ImGuiID> replacement.
 // - B) Use your own external storage: e.g. std::set<MyObjectId>, std::vector<MyObjectId>, interval trees, etc.
-// - C) Use intrusively stored selection (e.g. 'bool IsSelected' inside objects). Not recommended because you can't have multiple views
-//      over same objects. Also some features requires to provide selection _size_, which with this strategy requires additional work.

 // In ImGuiSelectionBasicStorage we:

 //   - in some cases we read an ID from some custom item data structure (similar to what you would do in your codebase)
 //   - in some cases we use Index as custom identifier (default implementation returns Index cast as Identifier): only OK for a never changing item list.
 // Many combinations are possible depending on how you prefer to store your items and how you prefer to store your selection.

 // See https://github.com/ocornut/imgui/wiki/Multi-Select for minimum pseudo-code example using this helper.
 // (In theory, for maximum abstraction, this class could contains AdapterIndexToUserData() and AdapterUserDataToIndex() functions as well,
 // but because we always use indices in SetNextItemSelectionUserData() in the demo, we omit that indirection for clarity.)
