NEW: Video rotation. Requires custom RotateFilter.dll must be installed (get VideoProcessingProjectInstaller.msi from http://videoprocessing.sourceforge.net).
EnableRotate() enables/disables the feature
Rotate() rotates the video
AutoRotate() - experimental, could produce unpredictable result. Rotates the video if screen orientation has been changed
ReverseAutoRotate() - if AutoRotate is on, changes rotation direction
