An X keyCode must be in the range XkbMinLegalKeyCode (8) to
XkbMaxLegalKeyCode(255).
The keyCodes we get from the kernel range from 0 to 127, so we need to
offset the range before passing the keyCode to X.
An X KeySym is an extended ascii code that is device independent.
The modifier map is accessed by the keyCode, but the normal map is
accessed by keyCode - MIN_KEYCODE. Sigh.
