+
+On high resolution displays(4k, 1080p) and tiny graphics games (640x480)
+show up very small so that they are unplayable. SCALED scales up the window
+for you. The game thinks it's a 640x480 window, but really it can be bigger.
+Mouse events are scaled for you, so your game doesn't need to do it.
+
+Passing SCALED to pygame.display.set_mode means the resolution depends
+on desktop size and the graphics are scaled.
