The old behaviour is available via waitKeyEx() call or
via setting of OPENCV_LEGACY_WAITKEY environment variable

checks whether the window exists and is visible. On QT closing a window
merley hides it, so the common hack for checking whether a window exists

exists = cv2.getWindowProperty(.., 0) >= 0

does not work.

also correctly forward spacing parameter in fontQt
