        postMessage does not send ImageData

        Add test for postMessage passing ImageData

        Update a few other tests to cover the fact that ImageData's constructor
        is now available on the window object.

        Implement serialisation of ImageData, and for testing reasons
        expose the ImageData constructor (which should already have
