Note: does not release mouse control when app loses focus. Escape to quit the program when done.
Note: makes use of Glenn Fiedler’s excellent PixelToaster library to handle setting up a window and managing a screen buffer and user input. I have been using it for several years now and thoroughly recommend it as a panacea for Windows programming neurosis. However it lacks the features necessary for proper mouse look.
