 Other Changes:
 
+- Added GetBackgroundDrawList() helper to quickly get access to a ImDrawList that will be rendered 
+  behind every other windows. (#2391)
 - Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigating to the menu layer.
 - DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types.
   We are reusing function instances for larger types to reduce code size. (#643, #320, #708, #1011)

  A: - You can create a dummy window. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags.
       (The ImGuiWindowFlags_NoDecoration flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse)
       Then you can retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
-    - You can call ImGui::GetOverlayDrawList() and use this draw list to display contents over every other imgui windows.
+    - You can call ImGui::GetBackgroundDrawList() or ImGui::GetOverlayDrawList() and use those draw list to display contents 
+      behind or over every other imgui windows.
     - You can create your own ImDrawList instance. You'll need to initialize them ImGui::GetDrawListSharedData(), or create
       your own ImDrawListSharedData, and then call your rendered code with your own ImDrawList or ImDrawData data.
