There are multiple features in css3-images that can transform an
image.  For example:

http://dev.w3.org/csswg/css3-images/#image-notation defines the
'ltr' and 'rtl' keywords which can cause an image to be flipped

http://dev.w3.org/csswg/css3-images/#image-orientation defines the
image-orientation property which can cause an image to be rotated.

It matters which one happens first, since doing them in a different
order produces different results when image-orientation computes to
90deg or 270deg.  css3-images should define a processing model that
says so.

(It may also be worth clarifying that all of this processing happens
before CSS transformations.)
