/*
* NOTE: The AT/MF keyboards can generate (via the 8042) two (MF: three)
* sets of scancodes. Set3 can only be generated by a MF keyboard.
* Set2 sends a makecode for keypress, and the same code prefixed by a
* F0 for keyrelease. This is a little bit ugly to handle. Thus we use
* here for X386 the PC/XT compatible Set1. This set uses 8bit scancodes.
* Bit 7 ist set if the key is released. The code E0 switches to a
* different meaning to add the new MF cursorkeys, while not breaking old
* applications. E1 is another special prefix. Since I assume that there
* will be further versions of PC/XT scancode compatible keyboards, we
* may be in trouble one day.
*
* IDEA: 1) Use Set2 on AT84 keyboards and translate it to MF Set3.
* 2) Use the keyboards native set and translate it to common keysyms.

** FIXME FIXME FIXME - web key code to scan code mapping
** This is really atrocious code. At the end of the day, we need to
** map keystrokes generated by the browser into the scan codes required
** by spice. This table was literally built by me pressing keys on my keyboard
** and typing the resulting value in by hand.
** I'm sure Europeans will hate me, and the Chinese will likely *never*
** talk to me.
** Converting keycodes to AT scancodes is very hard.
** luckly there are some resources on the web and in the Xorg driver that help
** us figure out what browser depenend keycodes match to what scancodes.
**
** This will most likely not work for non US keyboard and browsers other than
** modern Chrome and FireFox.
