Comment (by joemcgill):

 [attachment:33642.5.patch] is the same as above but adds a feature test
 for the `Imagick::setimageproperty()` and removes an unnecessary
 whitespace change from 'src/wp-includes/class-wp-image-editor.php' which
 had snuck into the other patches.

 I also added some clarifying inline docs for the step in
 `thumbnail_image()` that sets undefined alpha channels to opaque, which
 doesn't apply to most images, but can be a nice file savings with no
 visual difference when applicable.
