Subject: bin-layout: Use the actor align/expand flags
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6ddc694e68f827c9990d75a52af14cc911ff65ad;p=profile%2Fivi%2Fclutter.git

bin-layout: Use the actor align/expand flags

If an actor is set to expand, we use the actor's horizontal and vertical
alignment values instead of the BinLayout's.
