SDL 1.x: Add SDL_SetVideoMode flag that says the library should NOT automatically redraw the window contents when the window needs repainting. For the SDL 1.x X11 driver, this flag inhibits repainting the contents of the window on the X11 Expose event, which solves the problem with the DOS screen flickering while you resize the window in Linux. When the DOS prompt has been fully redrawn, remove the flag and handle the window as normal.
