Verify the basic capability to handle the 'path' element, and its data attribute (d) in combination with the straight-line path commands. Two pairs of concentric equilateral triangles are drawn using m and z. No l commands are used in this test as they are implied after an m or z command. The shapes are identical, with one stroked and one filled. The fill-mode default of "even-odd" means that the inner triangle is hollow.
The rendered picture should match the reference image exactly, except for possible variations in the labelling text (per CSS2 rules).
