Verify the basic capability to handle the stroke properties ("stroke", "stroke-width" "stroke-linejoin", "stroke-linecap",
"stroke-miter") in combination with straight-line path commands. The pair should be rendered as as two red line segments.
The upper segment should have round end caps. The lower segment should be chopped off where the two line segments meet.
The test uses the "path" element, as well as basic "fill" (solid primary colors), "stroke", "stroke-width",
"stroke-linejoin", "stroke-linecap", "stroke-miter", "font-family" (Arial) and "font-size" properties.
