title: css cursor url positioning
body: <p>I have some css like this:</p>
  
  <p><code>cursor: url("x.gif"), move;</code></p>
  
  <p>but the problem is that the image is not positioned right, I'd like to move it -15px up and left for example.  Is this possible?</p>
  
  <p>The center of a <code>cursor: move;</code> is the click point afaict and I'd like to use the center of my custom cursor image as well.</p>
