Subject: prevent crash with strict ana and non-mod-2 dimensions.
X-Git-Url: http://git.osdn.jp/view?a=commitdiff_plain;h=bd48bff38ee978ac17f47f9302c90ffa9d7cefe7;p=handbrake-jp%2Fhandbrake-jp-git.git

prevent crash with strict ana and non-mod-2 dimensions.
and make par computation in loose ana a little more accurate.
