Subject: fixed crash issue
X-Git-Tag: dali_1.3.47~2
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fuifw%2Fdali-toolkit.git;a=commitdiff_plain;h=91a8793e9d136c300cbd2c4f713ab60effcb6db1;hp=d4ba78a09cb848bbb8712e72eb21113fed6228da

fixed crash issue
If colorsBuffer and colorIndexBuffer are null, then crash occurs.
so if useDefaultColor is true, colorIndex must be 0u.
