title: understanding cocos2d anchorpoint/position
body: <p>Please tell me if I got this wrong.</p>
  
  <p>Anchor point is like a movable center of a sprite.<br>
  You specify a sprite's center by setting an anchor point.  </p>
  
  <p>Now you can place the sprite by specifying the position of the center.  </p>
  
  <p>ex)<br>
  anchor point = (1,1) : sprite's center is its right upper corner(I can think of it as "pinned at the right upper corner")<br>
      position = (screenWidth, screenHeight) : place the center(anchor point) at the (screenWidth, screenHeight) </p>
  
  <p>Resulting in a sprite aligned at the top-right corner of the screen.</p>
