vimix/UserInterfaceManager.cpp
Bruno b37d22ba47 Improved FrameGrabber with clock duration and priority strategies 
Keep track of actual FrameGrabber duration (different from timestamp). Two strategies for frame PTS: clock and framerate priorities. Implemented variable Framerate selection for VideoRecorder.  Integration of all this in UserInterface and Settings.
