title: Capturing mouse event data outside an iframe
body: <p>I am working on a Facebook app and have run into a situation where being able to capture whether or not the mouse has left the app's iframe would be really great info to have. I've tried playing with window.blur() and window.focus() in jquery but (for reasons regarding how my content renders at the moment) this only works in Firefox. I have considered using mousemove() to capture the x and y position of the mouse but it would appear that once the mouse leaves the iframe I'm out of luck.</p>
  
  <p>tl;dr I have an iframe that I have control of and a page it's embedded into that I don't. I need to capture the mouse movement/click/whatever outside my iframe and want to know if that's actually possible. Thanks!</p>
