* IME consists of two keyboard layers:
|

* - Low layer: "english" keyboard (qwerty, colemak, etc), stateless
|
||||
* - High layer: chinese/japanese/korean/etc. keyboard, stateful
|
||||
*
|
||||
* Input to the IME Keyboard layout is always GDX/LWJGL3 keycode (only LWJGL3 offers OS-Keylayout-independent keycodes)
