title: Will avoid drawing half pixel in HTML5 canvas improve speed?
body: <p>I am drawing a sprite (of a ball) on a canvas element. As the ball moves however, the x or y position of the ball may become a fraction, eg. (20.153; 63.638). When canvas is used to draw this image, it attempts to use transparent pixels to make the ball appear in it's position more accurately. </p>
  
  <p>I was wondering whether I should use <code>Math.round()</code> before drawing the ball to avoid the transparent pixel stuff, and possibly speeding up the game a lot. Will this help much? The game is a sorta complex pong game.</p>
  
  <p>The image below should help with my explanation:</p>
