* php5-imagick
*
* Provides:
* Animated image support (for image/gif at least)
* Animated GIF resize support
*
* Suggestions:
* After enabling the ImageMagick plugin, you might want to regenerate
* thumbnails for the newly support formats. This is easiest done with
* a script in the GNU social-bundled scripts directory:
* $ php scripts/clean_thumbnails.php
* Comments:
* Animated GIF resize requires setting $config['thumbnail']['animated'] = true;
*
* Bugs:
* Not even ImageMagick is very good at resizing animated GIFs.
* We are not infinitely fast, so resizing animated GIFs is _not_ recommended.
