   9  * - Tomb Raider 2 Demo:
  10  *   Playable using keyboard only.
  11  * - WingCommander Prophecy Demo:
  12  *   Doesn't get Input Focus.
  13  *
  14  * - Fallout : works great in X and DGA mode
  15  *
  16  * FIXME: The keyboard handling needs to (and will) be merged into keyboard.c
  17  *        (The current implementation is currently only a proof of concept and
  18  *         an utter mess.)
