//! Keyboard key IDs.
//!
//! See glfw.setKeyCallback for how these are used.
//!
//! These key codes are inspired by the _USB HID Usage Tables v1.12_ (p. 53-60), but re-arranged to
//! map to 7-bit ASCII for printable keys (function keys are put in the 256+ range).
//!
//! The naming of the key codes follow these rules:
//!
//! - The US keyboard layout is used
//! - Names of printable alpha-numeric characters are used (e.g. "A", "R", "3", etc.)
//! - For non-alphanumeric characters, Unicode:ish names are used (e.g. "COMMA",
//!   "LEFT_SQUARE_BRACKET", etc.). Note that some names do not correspond to the Unicode standard
//!   (usually for brevity)
//! - Keys that lack a clear US mapping are named "WORLD_x"
//! - For non-printable keys, custom names are used (e.g. "F4", "BACKSPACE", etc.)
