Description

Some tabs do not generate with custom layout.
I wrote a simple layout plugin that offsets alternating rows by 1.6mm, and rotates the first row by 180deg which looks like this:

However, it does not generate all tabs as specified by the KiKit:tab footprint, especially those on the right side of the board:

If I use the same layout plugin but remove the horizontal offset, the tabs do generate correctly.
The partition lines and bouding boxes all seem to be correct.

Steps to Reproduce

1. Download the attached board, config file, and plugin here: files.zip
2. Run: kikit panelize -p kikit_config.json main_bare.kicad_pcb panel.kicad_pcb
3. Check output to see that tabs are not generated on one side of the board

I just took your code and ran it - the partition line definitely doesn't look correct:

This is the reason why the tabs are not generated. I haven't been able to find the problem in the partition line generator so far. As a temporary workaround, I suggest building the partition line in the script manually. It should be straightforward for your layout.

Ahh that looks more like the actual partition line. How were you able to show the partition lines like that? When I run panel.debugRenderPartitionLines() at the end of the layout plugin I get this on layer User.Eco1:

Ah nevermind, I got it working now (when I ran panel.debugRenderPartitionLines() at the end of the buildPartitionLine function it shows the real parition line). Created the lines manually and now it generates the tabs correctly.
