+// dear imgui: Platform Binding for OSX / Cocoa
+// This needs to be used along with a Renderer (e.g. OpenGL2, OpenGL3, Vulkan, Metal..)
+// [ALPHA] Early bindings, not well tested. If you want a portable application, prefer using the GLFW or SDL platform bindings on Mac.
+
+// Implemented features:
+//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+//  [X] Platform: OSX clipboard is supported within core Dear ImGui (no specific code in this back-end).
+// Issues:
+//  [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..
