Avoid recomputing two consecutive identical 1D filters. If the arguments to the X and Y filter computation are identical, the results will be identical; copying is much faster than recomputing. With a change like https://codereview.chromium.org/183763047/ applied this speeds up BitmapScaleBench on Linux by around 10%.
