imagemagick preserves exif when scaling. GD does not. We do not want to preserve exif on thumbnails which we have rotated, as a browser reading the exif information could rotate them yet again. This checkin adds an abstract function to the generic photo driver which makes the behaviour consistent by stripping EXIF from imagick processed images. However, we will attempt to preserve any ICC colour profiles. See http://php.net/manual/en/imagick.stripimage.php
