+notes for OpenCV WinRT implementation:
+
+cvMain() in main.cpp
+  implements the image processing and OpenCV app control
+  it is running on a background thread, started by XAML
+  see file main.cpp
+  in the Application project
+
+class VideoCapture_WinRT:
+  implements the IVideoCapture interface from OpenCV
+  video is initialized and frames are grabbed on the UI thread
+  see files cap_winrt.hpp/cpp
+
+class HighguiBridge, a singleton
+  implements the OpenCV Highgui functions for XAML (limited at this time),
+  and also bridges to the UI thread functions for XAML and video operations.
+  see files cap_winrt_highgui.hpp/cpp
+
+class Video, a singleton
+  encapsulates the Media Foundation interface needed for video initialization and grabbing.
+  called through Highgui and XAML, only on the UI thread
+  see files cap_winrt_video.hpp/cpp
+
+threading:
+  requests from the OpenCV bg thread to the Video/XAML UI thread
+  are made through HighguiBridge::requestForUIthreadAsync(), which uses
+  the "progress reporter" method provided by the WinRT class
+  IAsyncActionWithProgress.  Also the bg thread is started by create_async().
+  see file MainPage.xaml.cpp
+  in the Application project
