Using Raw Input API in Unity

While working on a broadcast solution that used Unity to render and control a virtual character, I’ve faced a problem of capturing keyboard input events while the application is not in focus. It turned out that it’s not something doable using Unity’s input system, so I’ve assembled a C# wrapper over the Windows RawInput API to hook directly to the native input events.
