Now, `chres 640 480 2` can set the UI to HighDPI 640x480 at runtime. A real GUI for changing the display factor will come later. (`chres 640 480 2` followed by `chres 1280 960` is very fast since we don't have to re-allocate the framebuffer since both modes use the exact same number of physical pixels.)
