Comment (by joemcgill):

 [attachment:33642.2.patch] implements most of the custom compression
 settings for JPEGs from the RICG Responsive Images Plugin by adding a
 custom implementation of Imagick's `thumbnailImage()` method so that we
 can pass the `Imagick::FILTER_TRIANGLE` filter to the internal
 `resizeImage()` method, which is not possible through the default Imagick
 implementation (see [https://github.com/mkoppanen/imagick/issues/90
 related Github issue]).

 I've separated the functions that strip image profiles out to its own
 `strip_profiles()` method, which could be used by itself alongside the
 current `scaleImage()` method for resizing images.
