Subject: BorderlineColor allow Actor's OPACITY & MIX_COLOR
X-Git-Tag: dali_2.0.34~6^2
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fuifw%2Fdali-toolkit.git;a=commitdiff_plain;h=refs%2Fchanges%2F08%2F260908%2F2

BorderlineColor allow Actor's OPACITY & MIX_COLOR

Fix shader that borderline allow mix_color.

TRICK)
If you want to make contnet to be transperent and draw borderline only,
1. check OPACITY is bigger than 0.01f
2. make borderlineColor's alpha value bigger than 1.0f
