title: Translating mouse location to Object coordinates
body: <p>I'm trying to get basic mouse integration into a small demo using a Collada object. I am able to get the correct mouse x and y, but I don't know how to translate them into coordinates to be used for the object.</p>
  
  <p>I was hoping the GLGE function <code>duck.setLoc(mousepos.x, mousepos.y)</code> would convert from pixels, but that is not the case.</p>
  
  <p>What do I have to do to translate the 2D mousepos pixels into a 3D point?</p>
