Manipulate line width for hatching in matplotlib

The width of the hatch line in the matplotib graphics that occupy the hatch keyword is very thin. A few years ago I found several reports that a patch was made, but I still can’t figure out how to increase the width of the lines of the hatches. Is there any way to do this?

Unfortunately, setting the hatch line width in the Agg backend is currently not possible. The width is hardcoded in src / _backend_agg.cpp to "1.0":

hatch_path_stroke.width(1.0);

The same is true for other backends, such as a PDF file, but for these cases it might be easier to plan a monkey.
