+ This stuff is linked at the hip to the Window, since the window
+ processing is done in a thread kicked off in WinNtGopImplementation.c
+
+ Since the window information is processed in an other thread we need
+ a keyboard Queue to pass data about. The Simple Text In code just
+ takes data off the Queue. The WinProc message loop takes keyboard input
+ and places it in the Queue.
