    This is the fastest (and lowest quality) of all TTF rendering types.

    The resulting surface has a transparent background unlike

    will thus appear pixelated and difficult to read at small sizes. The

    when you need to render lots of text very quickly (e.g. if you're updating
    it every frame) or when you don't care about antialiasing.
   
    The 0 pixel is the colorkey for the resulting surface, giving a transparent
    background, and the 1 pixel is set to the text color. This allows you to
    change the color without having to render the text again. Palette index 0
    is not drawn when the returned surface is blitted to another surface (since
