there has been recent progress on that matter, you should check with Fred
Plourde. I think that two different approaches are being implemented,
mipmapping and box filtering. I would suggest using a summed area table for
box filtering. We'd be doubling the memory requirements of each image using
it but we would take almost no performance hit when doing downscale

Subject: [cairo] cairo_scale < 0.5 image clarity issue
referring to thread at
would like to know if there are any updates in cairo recently that improve
the scale clarity for < 0.5
currently to scale an image at 0.25 i create a temporary buffer and scale it
two times at 0.5 to get a better quality.
appreciate any inputs.
