Support screen and client rotation

Support screen and client rotation

In Tizen embedded system, two types of rotation are supported.
One is Window Rotation and the other is Screen rotation
Although their use-case are different, their rotation itself  almost works are same.
Real surface buffer is not rotated.
When rotation event is received from window server,
then internal contents are rotated and drawn with angle of the event.
This patch is to support the Tizen Rotation.
