Zooming and panning a DKDrawingView on a non retina display is very smooth. When on retina display the zoom/pan is very choppy and unresponsive. An objectDrawingLayer with no DkDrawableObjects does not behave this way, so the issues seems to be pointing at DKDrawabaleShapes or maybe DKRasterizer? I try setting NSGraphicsContext imageInterpolation to low in DKImageAdornment but still receive same behavior
