Comment 50 for bug 630639

I've submitted a patch to win32 Cairo so that it properly sends anything smaller than the device's smallest unit size as a hairline (0.001" works) so you can print directly to laser printers now: https://lists.cairographics.org/archives/cairo/2018-October/028767.html

Of course, these lines are hard to see, so I've also created a patch in Inkscape for a new display mode that makes "hairlines" (anything smaller than half a pixel on screen) more visible: https://gitlab.com/inkscape/inkscape/merge_requests/365
