Test for viewer capibility to handle the basics of the 'text-anchor' alignment property for 'text' and related elements.
The second group from the top contains sub-tests to verify that the interpreter handles text-anchor when the text is comprised of other text related elements, 'tspan', 'tref', and 'textPath'.
