title: What is "colorspace" in imagedata?
body: <p>Needed to do some pixel manipulation, but <code>ImageData</code> has changed. Now it has a <code>colorSpace</code> property.</p>
  <p>What is this, and how do I use it as normal?</p>
  <p>Just get an <code>ImageData</code> object in Chrome to reproduce.</p>
