Just double buffered the Windows console. What you are seeing here is two buffers: one which is empty, and one which has the text "Hello world!", and a pause of 1 second between buffer swapping.

This enables accelerated rendering in the Windows command line (By rendering to an off-screen buffer then simply swapping the active buffer), making things like advanced terminal applications in the Windows console possible.

And the best part- this is the first compilation of the project. Not a single run-time error. What a fucking satisfying accomplishment, honestly.
