[Tizen] (Partial update) Fix clipping area issue during window rotation

When window rotation events come from ecre, the result will be scored
at mPositionSize. and send event message to render thread.

BUt when the event is not comes to render thread,
the window's size value (mPositionSize) and
the scene's size value (scene.GetCurrentSurfaceRect()) mismatched.
So the clipping Rect will calculate wrong value.

This patch make clipping area always use current scene surface
