    Tests the basic support for markers. For the three tests, there should be two
    identical paths with markers drawn. The path on the left is rendered using the
    marker elements. The path on the right is rendered using the equivalent SVG,
    showing what the marked path should look like.

    This test is similar to the marker-001.svg test, but has some viewBox
    attributes that have a non-zero offset.

    The top test examines the basic support for the marker element and style. The
    markers are purple rectangles.

    The middle test examines the support for the different styles of marker
    properties. The "marker-start" property defines the marker to use at the first
    vertex of the marked path, in this case a purple rectangle. The "marker-end"
    property defines the marker to use at the last vertex of the marked path, in
    this case a blue triangle. The "marker-mid" property defines the marker to use
    at all vertices, other than the first and last, of the marked path, in this
    case a green circle.

    The bottom test examines the support for marker orientation along the path
    direction. The second vertex, the top right corner of the path, has a marker
    that is rotated 45 degrees, since that is the average of the horizontal and
    vertical segments each side. The last vertex, the bottom right corner of the
    path, has a marker rotated 90 degrees since that is the direction of the last
    path segment.
