prepare_window patch over sdk-2013.6
On Windows, using the following pipeline on an app-supplied window (instead of default window created automatically by the sink itself) leaks every time videoflip.method is toggled between values 0 (neutral) and 1 (rotate 90 CCW):
videotestsrc ! videoflip ! d3dvideosink
Attached patch adds calls to release the d3d device in prepare_window.
