drawImage vs CanvasPattern (v12)

Revision 12 of this benchmark created on

Description

For drawing sprites, how does fillRect() with a CanvasPattern compare to drawImage?

Preparation HTML

<canvas id="screen"></canvas>
<script>
  var ctx = document.getElementById("screen").getContext("2d");
  var image = document.createElement("img");
  image.src = "http://icons.iconarchive.com/icons/ph03nyx/super-mario/48/Retro-Mushroom-1UP-2-icon.png";
  
  var patternNoRepeat = ctx.createPattern(image, "no-repeat");
  var patternRepeat = ctx.createPattern(image, "repeat");
var PI2 = Math.PI * 2;
</script>
