+- Demo: Added full "Dear ImGui" prefix to the title of "Dear ImGui Demo" and "Dear ImGui Metrics" windows.
+- Backends: Add native Mac clipboard copy/paste default implementation in core library to match what we are
   dealing with Win32, and to facilitate integration in custom engines. (#2546) [@andrewwillmott]

   the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode
