Rendering Error
Rendering error in Opera 9.50 alpha.
On top there is a small horizontal line, this is the rendering error.
Because stroke-width is the smallest structure, there cannot be a smaller
structure as the stroke in the image. The horizontal line is clearly smaller as
the stroke-width. The error depends strongly on the height of the svg, the
viewBox and the choosen path, on the presence of the
z command, the stroke-linejoin,.
