RotatedOverlayImage class
Spans an image across three corner points.
Therefore this layer can be used to rotate or skew an image on the map.
The image is transformed so that its corners touch the topLeftCorner, bottomLeftCorner and bottomRightCorner points while the top-right corner point is derived from the other points.
