Helper function for positioning a window, based on the desktop size and the window's size.

Note: GLFW lacks the ability to get the window's actual size. The size you get back is always the size of the client area, not the whole window. As such, if you use this function to anchor the window to the right or bottom of the desktop, the window will be partially off-screen.
