Subject: [cairo] Downing scaling images

The best down scaler I have come across gdk-pixbuf with GDK_INTERP_HYPER.  Both the cairo scaler and gegl only do bilinear scaling.

  gdk_pixbuf_scale(px, spx, 0, 0, width_new, height_new, 0.0, 0.0, scale, scale, GDK_INTERP_HYPER);

I have a test C program comparing the three methods.
