Test for viewer correct handling of whitespace and the 'xml:space' attribute. There are four sub-tests, two for xml:space value "default" and two for value "preserve". In each test, the content of the 'text' element is written on multiple lines. The first test of each pair has indented text with leading space characters, tabs, etc. The second has no indentation, but a line break before the content and after it. There are no space (or other whitespace) characters at the ends of the lines.

The four test cases are self-descriptive. From the top; first, "default" value applied to 3 lines of content with indents, space characters, tabs, etc; second, "default" applied to two lines content with no indent; third, "preserve" applied to essentially the same content as first; fourth, "preserve" applied to essentially the same content as second.

In each test, the test string is in blue and the reference image is in black. The rendered picture should approximately match the reference image, however there is some question in the reference image concerning the exact amount of space in the long-space areas. Also, variations are possible in the text fonts and layout (per CSS2 rules).

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