This function uses the viewport and scaling functionality to allow a fixed logical resolution for rendering, regardless of the actual output resolution. If the actual output resolution doesn't have the same aspect ratio the output rendering will be centered within the output display.
If the output display is a window, mouse events in the window will be filtered and scaled so they seem to arrive within the logical resolution.
