Subject: screen: remove empty cell fallback
X-Git-Tag: upstream/3.0~28
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=68e64ecf6d4a0b5d959962d875a97694b6abc23a;p=platform%2Fupstream%2Flibtsm.git

screen: remove empty cell fallback

If we resize our screen, we guarantee that all cells are allocated. This
hasn't been true in the early times so we needed an empty cell during
rendering as fallback. It's no longer needed so remove it.
