Frame Buffer Rotation

For instance, if you make a vertical shot, you should rotate the camera 90 degrees, because if you just change the aspect ratio in a horizontal camera view, focal length will not work correctly, like in real life cameras. So to avoid this, you need to rotate camera and then lean your head to the side to see the image in viewport. The solution is to make a button in corona framebuffer that rotates it clockwise or anti clockwise
