title: What is a Blit in SDL?
body: <p>In the SDL wiki it says </p>
  
  <blockquote>
    <p>Use this function to perform a fast blit from the source surface to the destination surface. </p>
  </blockquote>
  
  <p>However that doesn't help me much.</p>
  
  <p>What does the term surface blitting mean in this context?</p>
