PIC backend broken
Steps to reproduce
echo 'graph {a -- b}' | dot -Tpic | pic | groff | ps2pdf - out.pdf
Expected Behaviour
I expected to see a simple 2 node graph rendered through groff to pdf.
Actual Behaviour
OS Version
FreeBSD 13.2
Graphviz Version
dot - graphviz version 8.1.0 (20230707.0739)
Additional info
I know I can adjust the scale factor, but that only seems to adjust line thicknesses and font size. The actual ellipses are way down in the bottom left corner, and the PIC code seems to validate that rendering. The sizing and position parameters for the ellipses are between 0 and 1, while the positioning of the lines and text are between 0 and 100, 2 orders of magnitude larger.
