title: When is an OpenCV imshow() window destroyed? (C++)
body: <p>Can someone help me with the behavior of windows created with the imshow() function?  I'm replacing a call to the older cvNamedWindow(), which required a window to be explicitly destroyed and cleaned up when you're done with it.  imshow, on the other hand, seems to require no cleanup and to close the window after a user keypress.  Do I have any control over that?</p>
