Benchmark: drawImage() benchmarking problem

Script Preparation code:

$sourceWidth = 100;
$sourceHeight = 100;
$sourceCanvas = document.createElement("canvas");
$sourceCanvas.width = $sourceWidth;
$sourceCanvas.height = $sourceHeight;
$sourceContext = $sourceCanvas.getContext("2d");
$sourceContext.fillStyle = "rgba(0,100,200,1)";
$sourceContext.fillRect(0, 0, $sourceWidth, $sourceHeight);

$destCanvas = document.createElement("canvas");
$destCanvas.width = 3000;
$destCanvas.height = 3000;
$destContext = $destCanvas.getContext("2d");

Tests:

Scale up to large canvas
$destContext.drawImage($sourceCanvas, 0, 0, $sourceWidth, $sourceHeight, 0, 0, 3000, 3000);
Scale up to medium canvas
$destContext.drawImage($sourceCanvas, 0, 0, $sourceWidth, $sourceHeight, 0, 0, 1000, 1000);
