title: Take OpenCV window and make full screen
body: <p>I am currently making an OpenCV project in C++ where I look for motion with a kinect and use that to cue a slideshow (sans recognition).  Currently, I am displaying the slideshow using OpenCV (as I've only had about a week to whip this up).  It looks good and its quick.  The only problem is that this is going to be on display for a big production and I can't really afford to have the window showing (I'm talking window decorations like the title bar and such).</p>
  
  <p>I need to get rid of the title bar.  I've done a lot of research, and I have found out that you can magically grab the window handle by calling cvGetWindowHandle("SlideShow"), but that is a void function, so I don't really know how I am supposed to get a handle from that to manipulate.  </p>
  
  <p>I'm developing this for both windows AND ubuntu, since it will end up on a windows machine, but I can only demo on a laptop running ubuntu.  </p>
  
  <p>If anyone can tell me how to take the window and render it fullscreen with a resized image to fill most if not the entire screen in either Windows or Ubuntu, I will be forever grateful. </p>
