- 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.
