1304 * If the window is completely unobscured, use bitblt's
1305 * to scroll. Even then, they're only used when doing partial
1306 * screen scrolling. When partially obscured, we have to fill
1307 * in the GraphicsExpose parts, which means that after each refresh,
1308 * we need to wait for the graphics expose or Noexpose events,
1309 * which ought to make things real slow!
