1//! There are quite a few different notions for keycodes. And most of them are `u32` so it does get
2//! very confusing...
3//! Basically
4//!   - Wayland server sends a scancode `key` of type `c_uint`
5//!   - `key + 8` becomes a `xkb` scancode of type `xkb_keycode_t`
6//!   - We feed this to `xkb` to get a `keysym` of type `xkb_keysym_t`
7//!     - The `keysym` can be modifier-dependent: `Shift + Key1` can be translated to either `Key1`
8//!       (without modifier) or `Exclam` (with modifier)
9//!   - We then feed the `keysym` to `translate_keysym` to get a Miniquad `Keycode`
10//!
11//! Note that the default Miniquad behavior is without modifier; there is not even a Keycode for
12//! `Exclam`. So we must provide the unmodified `keysym` or we will get a `Keycode::Unknown`.
13//!
14//! On the other hand, the modified `keysym` is useful when we want to translate it into the
15//! underlying character.
