Benchmark: Test save/restore

HTML Preparation code:

<canvas id="canvas" width="800" height="300"></canvas>

Script Preparation code:

$canvas = document.getElementById('canvas');
$context = $canvas.getContext('2d');
$context.clearRect(0, 0, 800, 300);

$iterations = 500;

Tests:

resetTransform
for (let i=0; i<$iterations; ++i) { $context.fillStyle = 'rgba(100,150,200,0.9)'; $context.fillRect(0, 0, 1, 1); $context.translate(50, 50); $context.rotate(50 * Math.PI / 180); $context.resetTransform(); }
Save/restore
for (let i=0; i<$iterations; ++i) { $context.save(); $context.fillStyle = 'rgba(100,150,200,0.9)'; $context.fillRect(0, 0, 1, 1); $context.translate(50, 50); $context.rotate(50 * Math.PI / 180); $context.restore(); }
