Detailed Description

KeyEventResponder implements the NSTextInputClient protocol as is required by the macOS text input manager.

The macOS text input manager is invoked by calling the interpretKeyEvents method from the keyDown method. Keyboard events are then evaluated by the macOS input manager and valid text input is passed back via the insertText:replacementRange method.

This is the same approach employed by other cross-platform libraries such as SDL2: https://github.com/spurious/SDL-mirror/blob/e17aacbd09e65a4fd1e166621e011e581fb017a8/src/video/cocoa/SDL_cocoakeyboard.m#L53 and GLFW: https://github.com/glfw/glfw/blob/b55a517ae0c7b5127dffa79a64f5406021bf9076/src/cocoa_window.m#L722-L723
