Comment 5 for bug 168275

A single rectangle would be a better example..

<svg
   width="101"
   height="101">
  <rect
     width="100"
     height="100"
     x="0.5"
     y="0.5"
     style="fill:#550000;stroke:#003855;stroke-width:1" />
</svg>

Export to Pdf and zoom in at the top and bottom. You will see the phantom
white line at the bottom and that the top border is too thin. The error
clearly sits in the coordinate change (and probably does so in other
exporters as well since i used the internal pdf writer and the bug reporter
attached a cairo pdf)

Here are the important lines:

/MediaBox [ 0 0 80.80000305 80.80000305 ]
stream
0.8 0 0 -0.8 0 81 cm

The 81 should be 80.8
