The image scaling task has been moved to Ubuntu 8.04 servers. Along the way, some software versions have changed:
ImageMagick upgraded from 6.2.8 to 6.3.7 (Q8 custom build) Rsvg from 2.14.0 to 2.22.2 (with security patch) FFmpeg: upgraded from patched r10291 to Ubuntu stock DjVu: upgraded from 3.5.17 to 3.5.20 Fonts: generally upgraded with more coverage
Originally I only tested the merged rsvg security patch to make sure it was secure, and indeed, rsvg-convert still can't read any local files. But it also can't read its input file specified on the command line. So I'm using stdin for now.
Keep an eye out for odd rendering of SVGs, e.g. bad font selection. Submit a bug if you see anything like that.
