The image test case checks to see if the basic image formats are supported. The upper right has an JPG image the lower right has a PNG image. They are the same image. The upper left is an SVG image, there should be a red rectangle in the upper right and a yellow rectangle in the lower left. Those positions are relative to the upper left of the entire canvas. If any of the components are missing, then an image format is not being properly supported.

The rendered picture should match the reference image, except for possible variations in the labelling text (per CSS2 rules).

The test uses the 'rect' element, as well as basic fill (solid primary colors), stroke (black 1-pixel lines), font-family (Helvetica) and font-size properties.
