title: html2canvas not support transform property?
body: <p>I build an image editor in javascript for my customer and we issue one huge problem. When we want to generate image where is some text rotated, canvas not generate full image with all contents over background.</p>
  
  <p>Here is example:</p>
  
  <p><a href="https://i.stack.imgur.com/S6fay.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/S6fay.png" alt="enter image description here"></a></p>
  
  <p>When I click on save button I get empty background like this:</p>
  
  <p><a href="https://i.stack.imgur.com/7KsRF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7KsRF.png" alt="enter image description here"></a></p>
  
  <p>On other way, when I just add content and NOT do rotation, transform not exists in CSS, I can change color of text, change font, change background and all will look nice like on this example:</p>
  
  <p><a href="https://i.stack.imgur.com/gSM6b.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gSM6b.png" alt="enter image description here"></a></p>
  
  <p>Result is perfect:</p>
  
  <p><a href="https://i.stack.imgur.com/hXfwi.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hXfwi.png" alt="enter image description here"></a></p>
  
  <p>Here is my code:</p>
  
  <pre><code>function generateImage(canvas, width){
      var img = new Image();
      img.crossOrigin = "Anonymous";
      img.width = width;
      img.height = (img.width / ( 16 / 9 ));
      img.src = canvas.toDataURL();
      img.align = 'middle';
      img.class = 'img-responsive';
      img.style.width = '100%';
      img.style.maxWidth = width;
  
      document.body.appendChild(img);
  }
  
  html2canvas($this, {
      onrendered: function(canvas) {
          generateImage(canvas, ($this.width()+2));
      },
      width: $this.width()+2,
      height: $this.height()+2
  });
  </code></pre>
  
  <p>The main question is:</p>
  
  <p>Is there a way to add in canvas CSS transition support to can render proper full image or some 3D canvas drawing which work properly?</p>
