+
+// Multi-selection system
+// Documentation at: https://github.com/ocornut/imgui/wiki/Multi-Select
+// - Refer to 'Demo->Widgets->Selection State & Multi-Select' for demos using this.
+// - This system implements standard multi-selection idioms (CTRL+Mouse/Keyboard, SHIFT+Mouse/Keyboard, etc)
+//   with support for clipper (skipping non-visible items), box-select and many other details.
+// - Selectable(), Checkbox() are supported but custom widgets may use it as well.
+// - TreeNode() is technically supported but... using this correctly is more complicated: you need some sort of linear/random access to your tree,
+//   which is suited to advanced trees setups also implementing filters and clipper. We will work toward simplifying and demoing it.
+// - In the spirit of Dear ImGui design, your code owns actual selection data.
+//   This is designed to allow all kinds of selection storage you may use in your application e.g. set/map/hash.
+// About ImGuiSelectionBasicStorage:
+// - This is an optional helper to store a selection state and apply selection requests.
+// - It is used by our demos and provided as a convenience to quickly implement multi-selection.
+// Usage:
+// - Identify submitted items with SetNextItemSelectionUserData(), most likely using an index into your current data-set.
+// - Store and maintain actual selection data using persistent object identifiers.
+// - Usage flow:
+//     BEGIN - (1) Call BeginMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (2) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 6.
+//           - (3) [If using clipper] You need to make sure RangeSrcItem is always submitted. Calculate its index and pass to clipper.IncludeItemByIndex(). If storing indices in ImGuiSelectionUserData, a simple clipper.IncludeItemByIndex(ms_io->RangeSrcItem) call will work.
+//     LOOP  - (4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.
+//     END   - (5) Call EndMultiSelect() and retrieve the ImGuiMultiSelectIO* result.
+//           - (6) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 2.
+//     If you submit all items (no clipper), Step 2 and 3 are optional and will be handled by each item themselves. It is fine to always honor those steps.
+// About ImGuiSelectionUserData:
+// - This can store an application-defined identifier (e.g. index or pointer) submitted via SetNextItemSelectionUserData().
+// - In return we store them into RangeSrcItem/RangeFirstItem/RangeLastItem and other fields in ImGuiMultiSelectIO.
+// - Most applications will store an object INDEX, hence the chosen name and type. Storing an index is natural, because
+//   SetRange requests will give you two end-points and you will need to iterate/interpolate between them to update your selection.
+// - However it is perfectly possible to store a POINTER or another IDENTIFIER inside ImGuiSelectionUserData.
+//   Our system never assume that you identify items by indices, it never attempts to interpolate between two values.
+// - If you enable ImGuiMultiSelectFlags_NoRangeSelect then it is guaranteed that you will never have to interpolate
+//   between two ImGuiSelectionUserData, which may be a convenient way to use part of the feature with less code work.
+// - As most users will want to store an index, for convenience and to reduce confusion we use ImS64 instead of void*,
+//   being syntactically easier to downcast. Feel free to reinterpret_cast and store a pointer inside.
