Very slow rendering on PageDrawer.shadingFill

    Details

      Description

      The PDF contains many effectively very small shadings, the light cones. As the gradient painting for each light cone is applied on the whole image, rendering is very slow: 29 of 33 seconds are spent in shadingFill.
