title: interactor issue using Chrome
body: <p>I'm using Chrome 24.0.1312.56 (portable version) and  25.0.1364.97 m (installed version) to display some 3D contents. The interation in the 3D scene is not optimal. When I click and move slowly, there is no rotation in the scene. If I move quicker, the interaction starts. It means that I have to interact relatively quickly to mo the 3D scene. This behavior is not seen on firefox 18.0.2.
  It looks like there is a minimal movement (or speed movement) under which, the event is thrown away.</p>
  
  <p>The "bug" is worst when the move is in the Y axis of the viewport. Moving in the X axis is better, but not "normal".</p>
  
  <p>Is chrome catching or not propagating some moves to xtk? Is there a threshold for the minimal move or speed?</p>
  
  <p>Thanks,
  Laurent.</p>
