title: Output values in Pixel Blender (trace)
body: <p>I'm absolutely new to Pixel Blender (started a couple of hours ago).</p>
  
  <p>My client wants a classic folding effect for his app, I've shown him some example of folding effect via masks and he didn't like them, so I decide to dive in Pixel Blender to try to write him a custom shader.</p>
  
  <p>Thx God I've found <a href="http://superflashbros.net/2010/06/28/a-real-page-turner/" rel="nofollow">this one</a> and I'm modyfing it by playing with values. But how can I trace / print / echo values from Pixel Blender ToolKit? This would speed up a lot all the tests I'm doing.</p>
  
  <p><a href="http://blog.joa-ebert.com/2009/02/27/pixelbender-development-tool/" rel="nofollow">Here</a> i've found in the comments that it's not possible, is it true? </p>
  
  <p>Thx a lot</p>
