Output pixel dimensions
This is more of a note to self since it probably can't be fixed. But when exporting the attached file to PNG or SVG, the segment borders are not the same size on all four sides. The line thickness is 12, so the segments should be 6 pixels wide. In the export area, this is once again cut in half, meaning there should be a 3px orange/brown border on all four sides.
I tried exporting as SVG and then converting the SVG to PNG using Inkscape, but got identical results. In Inkscape you can see that the bottom and right segments are thicker.
It's annoying for artists, but probably doesn't affect anyone else.
