title: html canvas shadow being applied to everything
body: <p>If you define a shadow ONCE, then it applies to all "graphics" on the canvas from thereon after (which is what it's supposed to do).</p>
  
  <p>Sample:
  <a href="http://flanvas.com/development/flanvas/test.html" rel="noreferrer">http://flanvas.com/development/flanvas/test.html</a></p>
  
  <p>Does anyone know best practice to turn the shadow off after you've used it? I'm setting shadowColor to "rgba(0,0,0,0)" which is a no-alpha black. I'm sure there is a better way.</p>
  
  <p>case sample: The text is also getting a shadow. I'm using the no-alpha black to combat this for now.
