Subject: scene-loader.example fixes.
X-Git-Tag: dali_2.0.8~7
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fuifw%2Fdali-demo.git;a=commitdiff_plain;h=15b2dcc5584bbd91668948108a4241f7ca3a742a

scene-loader.example fixes.

- main() is exported using DALI_EXPORT_API, so that Android may see it;
- refined rotation code and made the scaling factor a more meaningful
  quantity;
