title: Can a canvas handle double numbers as points?
body: <p>Is a <code>canvas</code> capable of handling <code>double</code> numbers like <code>0.5, 10.4</code> etc? Or would this be rounded internally to an integer (if yes, how?).</p>
  
  <p>I'm asking because I think that elements on a canvas are represented as pixels.</p>
  
  <p>And as a pixel is always size <code>1x1</code> (correct me if I'm wrong), is there any advantage of more accurate drawing if I supply <code>double</code> values to a canvas function rather than <code>integer</code>?</p>
