  • Revision ID: matt.giuca@gmail.com-20090224020203-aqdcjnsj6y7wl32o
Added a new look to the IVLE header bar. Mmmm... Web 2.0.
Added top-level directory image-source, containing SVG and script files for
    generating the images.
ivle/webapp/coremedia/images: Added 'chrome' directory containing the rendered
    images.
Modified ivle/webapp/base/ivle-headings.html and
    ivle/webapp/coremedia/ivle.css to support the new images.
    Note that the H1 and H2 at the top of the page are no longer displayed
    (and their custom styles have been removed). There is a heading image
    instead.
