    [broadway] Emulate hardware keycodes in keyboard events
    
    We can't really know the client side keymaps, so we use the keysym
    as the hardware keycode (essentially claiming to have a keyboard with
    one key for all possible keysyms). This is not ideal, but its hard to
    do better with no knowledge of the client side keyboard mappings.
    (And html keyboard events suck badly...)
