* @brief Scancode handling
*
* Convert between RDP scancodes and X11 keycodes.
*
* RDP scancodes are largely the same as Windows scancodes. These are
* indirectly documented in the Microsoft "Keyboard Scan Code Specification",
* Rev 1.3a (March 16th 2000) and are otherwise known as "Scan code set
* 1" scancodes. This document no longer appears to be available directly from
* the Microsoft website.
*
* X11 keycodes are the X11 equivalent of RDP scancodes. In general, these
* are specific to an X server. In practice however, these are nowadays
* handled by the XKB extension and only two sets are in common use:-
* - evdev : Linux, FreeBSD and possibly others
* - base : Everything else.
*
* This module presents a single source of truth for conversions between
* RDP scancodes and X11 keycodes.
