// ImGui Platform Binding for: OSX / Cocoa
// dear imgui: Platform Binding for OSX / Cocoa
// This needs to be used along with a Renderer (e.g. OpenGL2, OpenGL3, Vulkan, Metal..)
// [BETA] Beta bindings, not well tested. If you want a portable application, prefer using the Glfw or SDL platform bindings on Mac.
// [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]..
// [ ] Platform: Mouse cursor shapes and visibility are not supported (see end of https://github.com/glfw/glfw/issues/427)
// [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2019-07-21: Readded clipboard handlers as they are not enabled by default in core imgui.cpp (reverted 2019-05-18 change).
// 2019-05-28: Inputs: Added mouse cursor shape and visibility support.
// 2019-05-18: Misc: Removed clipboard handlers as they are now supported by core imgui.cpp.
// 2019-05-11: Inputs: Don't filter character values before calling AddInputCharacter() apart from 0xF700..0xFFFF range.
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
// 2018-07-07: Initial version.
