* [ maze ] ...

* modified: [ 03-08-15 ] Ge van Geldorp <ge@gse.nl>
* ported to ReactOS
* modified: [ 94-10-8 ] Ge van Geldorp <Ge.vanGeldorp@lr.tudelft.nl>
* ported to MS Windows
* modified: [ 3-7-93 ] Jamie Zawinski <jwz@lucid.com>
* added the XRoger logo, cleaned up resources, made
* grid size a parameter.
* modified: [ 3-3-93 ] Jim Randell <jmr@mddjmr.fc.hp.com>
* Added the colour stuff and integrated it with jwz's
* screenhack stuff. There's still some work that could
* be done on this, particularly allowing a resource to
* specify how big the squares are.
* modified: [ 10-4-88 ] Richard Hess ...!uunet!cimshop!rhess
* [ Revised primary execution loop within main()...
* [ Extended X event handler, check_events()...
* modified: [ 1-29-88 ] Dave Lemke lemke@sun.com
* [ Hacked for X11...
* [ Note the word "hacked" -- this is extremely ugly, but at
* [ least it does the job. NOT a good programming example
* [ for X.
