title: Does scaling a canvas affect the number of pixels getDataURL() returns?
body: <p>I'm experimenting with using a canvas as an image cropping preview and then use <code>getDataUrl()</code> to retrive the data to send to the server via an AJAX post.</p>
  
  <p>I've explicitly set the initial width and height of the canvas in the HTML using pixels, but I scale the canvas using percentages in CSS to fit a responsive design.</p>
  
  <p>While it would make sense that scaling a canvas element wouldn't affect the pixel content, I'd like to be certain. Will scaling a canvas element, not its content, return a different number of pixels than what I initially set?</p>
