  • summary

    Adds magnification on a portion of an image element

  • description

    An unobtrusive way to add an unstyled overlay
    above the srcNode image element. The overlay/glass is a
    scaled version of the src image (so larger images sized down
    are clearer).
    
    The logic behind requiring the src image to be large is
    "it's going to be downloaded, anyway" so this method avoids
    having to make thumbnails and 2 http requests among other things.
