I've just 'darcs send' a demo application I've created -patch name
was: 'new demo - scaling'. It uses the seam carving algorithm
(http://www.seamcarving.com/) for image resizing - eg: try File|Seam
Carve menu and select eg: 576x200 as the desired image size. Please
let me know if you think it's a good idea to include it as a demo. If
the patch somehow didn't get to you (it was my first time with darcs)
I can send it by email - please let me know.
