Bug report

Bug summary

The baseline images for the rgba_markers test (rgba_markers.{png,pdf,svg}) clearly show differences in rendering between agg, pdf and svg:

top left is the svg baseline rendered by inkview (inkscape) 0.92.2, top right is the png baseline, bottom left is the pdf baseline rendered by okular 17.08.3, bottom right is the pdf baseline rendered by gs 9.22 (gs is used by the testing framework to rasterize the pdf for image comparisons).

Code for reproduction

N/A

Actual outcome

On the right subplot, whether the central blue disk overlaps with the edge red circle depends on the backend... and, for the case of pdf, also on the renderer (so that part may possibly be a bug in eother okular or gs, but at least svg and png should not be different).

Expected outcome

All three backends should render hatching in a similar manner.
