So perhaps an X11 expert=20 could investigate doing that for the X Window System, when ImageMagick=20 scaling is not available or not used. My impression is that the Xrender=20 extension (introduced in 2000) is reasonably popular among X11 servers=20 these days. Scaling on the server could also be faster (e.g., with hardware=20 acceleration) and/or more reliable, so quite possibly it'd be better to=20 use Xrender to scale even if ImageMagick is available.
