title: Qt QGraphicsSvgItem renders too big (0.5 unit on each side)
body: <p>If I draw an SVG item at (0, 0) with 64x64, the actual displayed SVG item is from (-0.5, -0.5) with 65x65. I measured this by drawing the boundingbox behind the SVG item. And the SVG item is sticking out at all sides by a half unit on the QGraphicsScene.</p>
  
  <p>Can I remove this effect? I have set the pen to NoPen.
  I could scale it down, but that would be quite unprecise (since width and height need different scaling, which is hardly possible). How can I fix this issue?</p>

  <p>As you can see, the brown boxes (SVG) stick out over the grey area (bounding box). The bounding box is confirmed with Inkscape.</p>
  
  <p>Thanks</p>
