Well, in ImageMagick you have 15 different algorithms to choose from, but the
default (lanczos) is very good. See:
http://www.imagemagick.org/script/command-line-options.php#filter

In gimp you have linear, cubic and in newer versions, lanczos. You set the
default in File->Preferences->Tool Options->Scaling.

Yes !

Gimp, "Scale Image" should be fine (menu Image, item "Scale Image").
You can choose the interpolation method (None, Linear, Cubic).

Yes, through Preferences, Image tab, "Zoom quality".
Choose for instance "nearest" if you want to spped up image resizing,
but you'll get a lower quality.

Thanks to all who helped with my Anti-alias question. I have it working 
in both gimp and image magick and it looks great.
