Right now, when passing a large image into a filter that will process it for output to a much smaller destination, the filter will just sample from locations corresponding to pixels in the final image. This leads to sharp discontinuities, rather than a smoother scaledown, so a better way of scaling these images to provide smoother interpolation needs to be used.
