  92                 Verifies implicit rendering order (paragraph 3.3) and grouping mechanism (paragraphs 3.4).
  93                 It also validates basic Shape, Image and text rendering.
  94             </p>
  95             <p>
  96                 This test renders 3  elements: a text string "SVG", then
  97                 a shape, then an image. Because of their definition order and coordinates, the image
  98                 should be on top of the rectangle and the rectangle on top of the text. The
  99                 test validates that groups are conceptually rendered offscreen before being
 100                 rendered on the canvas. This is done by grouping the same overlapping objects and
 101                 rendering the group at half opacity. The background pattern (vertical stripes) should
 102                 show throw all the group elements. However, none of the "SVG" should show through the
 103                 rectangle and none of the rectangle should show through the image.
 104             </p>
 105             <p>
 106                 Prerequisites: the test assumes proper handling of the fill stroke, stroke-width,
 107                 opacity, font-size rendering properties. It uses the rect, line, text and image elements, as
 108                 well as all the elements required for the test template. To ensure that the text string is
 109                 overlapped by the other elements and to avoid a dependency on system fonts, an SVG font is used.
 110             </p>
 111             <p>
 112                 The rendered image should match the reference image exactly.
