title: A bunch of questions about SDL
body: <p>I'm starting a little RTS game with SDL and here are some questions:</p>
  
  <ul>
  <li>I work with small sprites, is
  there a way of displaying the screen
  x2 with scanlines ? I tried zooming
  it with rotozoom but it slows down
  the game and I would like to avoid scaling my sprites by hand.</li>
  <li>How can I switch
  between fullscreen and windowed while
  running ? I found the
  <code>SDL_WM_ToggleFullScreen</code> function but
  it doesn't seems to work on Windows
  according to SDL doc.</li>
  <li>In order to put my own cursor I load a sprite with my pointer and
  make it follow the mouse. But I would
  also like to lower the framerate with
  <code>SDL_Delay</code> and doing so makes the
  pointer movements not smooth. The SDL
  cursor doesn't seemed influenced by
  the application framerate is it a
  better solution to use it and if so, is there a way of using a picture instead of a weird mask ?</li>
  <li>Is there a better way of limiting framerate ?</li>
  <li>How can I tinte a surface (like with <code>draw_lit_sprite</code> in
  Allegro)</li>
  </ul>
