+/******************************* Debugger API Notice ********************************
+  Those three calls, and the debug_enable flag in the constructor, have been added to
+  help debugging a WindowScreen application without a cross-developement platform or
+  the use of serial debug output.
+
+  To use them, you need to :
+  - enable the debug mode by setting the debug_enable flag of the constructor to "true".
+  - register all threads that could be accessing the screen directly at any time. To do
+    that, call RegisterThread after spawning the new thread and before resuming
+	it (you should never draw from the Window thread itself, neither register it).
+  - launch your application from Terminal. The GameKit will first swicth to another
+    workspace before opening the WindowScreen. If you launch from workspace 0 [Alt-F1],
+	it will choose the workspace 1 [Alt-F2]. For any other workspace, it will choose
+	the previous one (for example, for workspace 3 (Alt-F4), it will choose workspace 2
+	[Alt-F3]).
+
+  Then :
+  - You can use printf(...) anywhere to display informations that will be logged in the
+    Terminal window. You can go back to the Terminal Window at any time (using the
+	correct Alt-F?? key). Switching workspace will automatically suspend all the thread
+	you registered and save the graphic context. Switching back to the WindowScreen
+	workspace will restore everything and resume your application.
+  - If you need to save and restore more states when your application is suspended and
+    resumed, you can overwrite the ForceSwitchForDebug() method. This function is called
+	with active == true just after suspending your app, and active == false just before
+	resuming it.
+  - You can suspend your application by calling the Debugger() method. This will also
+    switch to the Terminal workspace. Then you can resume by just switchng back to the
+	WindowScreen workspace (using the good Alt-F?? key). It's better not to call Debugger()
+	with the WindowScreen locked.
+
+  In case of crash :
+  - Use the safety short-cut : All the left modifiers (Ctrl, Shift, Option, Command, Alt
+    or equivalents) of your keyboard and F12. That should send you back to 640x480, and
+	the debugger terminal should be visible (and usable) if any.
+  - Then, you can also switch to your Terminal workspace to check the last printf infos.
+  - After you got (we hope) more information about your (or our :-) bug, quit the debugger
+    window. Then you should be able to change your code and run your application again.
+	In any case, check the Error() function immediately after the WindowScreen constructor.
+	A bad error code will mean that the GameKit is in a inconsistent state, and then you
+	have better to reboot your machine. If you don't wnat to reboot, you can also try to
+	run your application in a different workspace.
+
+	It's far to be perfect, but we hope it will still help.
+
+	The Debug API will not be support after the Preview Release (replaced by the debug
+	API in the new WindowScreen class).
