/* To add a new mode:

    - Define a function `new_os(dpy,win)' that returns a `bsod_state' struct.
    - Draw on the window to set up its frame-zero state.  This must be fast:
      no sleeping or long loops!
    - Populate the bsod_state structure with additional actions to take by
      using the various BSOD_ macros.  Note that you can control the delays
      when printing text on a per-character or per-line basis.
    - Insert your function in the `all_modes' table.
    - Add a `doXXX' entry to `bsod_defaults'.
    - Add fonts or colors to `bsod_defaults' if necessary.

   Look at windows_31() for a simple example.

   Look at linux_fsck() for a more complicated example with random behavior.

   Or, you can bypass all that: look at nvidia() for a really hairy example.

/* Atari ST, by Marcus Herbert <rhoenie@nobiscum.de>
   Marcus had this to say:

	Though I still have my Atari somewhere, I hardly remember
	the meaning of the bombs. I think 9 bombs was "bus error" or
	something like that.  And you often had a few bombs displayed
	quickly and then the next few ones coming up step by step.
	Perhaps somebody else can tell you more about it..  its just
	a quick hack :-}

   UNIX).  Both are very much like MULTICS which Honeywell got from GE.

   HVX ("High-performance Virtual System on Unix") is an AIX application
