Subject: Fix for TextView's snapshot mode
X-Git-Tag: dali_1.0.0~6
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fuifw%2Fdali-toolkit.git;a=commitdiff_plain;h=6943985ad1847a18a137d04467e8e0e9bff91620

Fix for TextView's snapshot mode

TextInput is enabling scroll mode. Scroll mode enables snapshot mode which
causes a drop of text quality due to a usage of a wrong blending function.

Use the correct blending function.
