Generate without zones refill

[radoslav006]

Describe the bug
Tool refills out-of-date zones even if one select to not do that.

To Reproduce
Steps to reproduce the behavior:

1. Project without refilled zones.
2. Click "Genereate".
3. Tool asks "Zones fills are out-of-date. Refill?".
4. I choose "Continue without refill".
5. After gerbers inspections it turns out that zones are refilled anyway.

Expected behavior
Zones shall remain unfilled.

That is a bug in KiCAD itself and needs to be fixed on the KiCAD side: https://gitlab.com/kicad/code/kicad/-/issues/13135

I see. I just locally commented out the zone refilling for myself.
Maybe this could be also a solution for your repo; in that way the user has choice to fill the zones or not before launching the plugin. The other option is to detect unfilled zones and provide a custom wx pop-up that will ask user to fill or not. But I am not sure if this could be achieved with KiCad API - btw. is there any sensible API documentation available? I am willing to contribute, but have no knowledge of the KiCad API.

If you ask what a mad man do not refill the zones before production, I can show you what a nice copper balancing can be achieved with this (not connected copper balancing is important from a signal integrity perspective) :)

In the end, you were aware of the problem, so the issue could be closed then, I suppose.

I think we could add another option in the settings that lets the user turn off the auto filling!

[radoslav006]

Indeed, a good idea.

Done!
