Yes, but theoretically it gives better results. There are three algorithms in Jeff's patches: integer-box, box and lanczos. The first one is the fastest but it gives the worst quality, lanczos provides the highest quality but it's slower than the others. Jeff suggested me to use box since it provides quite good quality with a reasonable performance.

The problem is only in the image backend, so we don't use it when printing.
