    API: map-to-image and create-similar-image

    A common requirement is the fast upload of pixel data. In order to
    allocate the most appropriate image buffer, we need knowledge of the
    destination. The most obvious example is that we could use a
    shared-memory region for the image to avoid the transfer cost of
    uploading the pixels to the X server. Similarly, gl, win32, quartz...

    The other side of the equation is that for manual modification of a
    remote surface, it would be more efficient if we can create a similar
    image to reduce the transfer costs. This strategy is already followed
    for the destination fallbacks and this merely exposes the same
    capability for the application fallbacks.
