Fix a first set of issues with rotation transition animations

When pushing four view controllers with such transition animations with a rotation of M_PI_2, the width becomes 0. When popping and resurrecting view controllers, this leads to issues since the camera will be sent to infinity, not to 4 * width. Use 4 * height instead
