Bug report

Bug summary

The baseline images for the test_clipping test (clip_path_clipping.{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

• the colors of the stars are slightly different between png and svg.
• the pdf backend render the stars as empty rather than filled.

Expected outcome

All three backends should render hatching in a similar manner.

(As a side note, mplcairo generates pdf and svg that render like the png.)
