Subject: [PATCH] [Tizen](Partial Update) partiall update after window rotation
 works well.

Currently, mDamagedRects should be "rotated" rects,
and others (clippingRect, mDamagedBufferRects) are not be rotated.

But current clippingRect merged by rotated rects.

This patch make clippingRect calculate well.

And also, if clippingRect become empty, mDamagedRects should be cleared.
