Changed logic of the DWM capture which tries to keep the window to capture on it's location, so less movement is visible. Also added a BoxBlur which might be a faster replacement of the CreateBlur (which is Gaussian), but the quality needs to be checked. For the BoxBlur the BitmapBuffer is extended with a few new tricks.
