    Description

      The QSvgRenderer produces noticeable banding when rendering gaussian blur, for example for drop shadows. See the attached image

       

      The image on the left hand side was produced by QSvgRenderer. The image on the right hand side was produced by running `inkscape --export-type="png" -w 352 -h 352 default.svg`.

      See also the attached demo.
