RFC/RFE: integrate transmission line simulator from AlterPCB?

[eqvinox]

Just a random idea: AlterPCB (which seems to be dead, last activity in 2018) has a pretty nice transmission line simulator

https://github.com/MaartenBaert/alterpcb-tlinesim

It's a 2D FEM solver for calculating impedance and propagation velocity of PCB traces. (There's a screenshot on the webpage above.) It's licensed under GPLv3, written in C++ and provides a Qt GUI.

It might be worth rewriting this to use Gtk and integrate into Horizon, maybe as some type of optional add-on? The stackup editor could track some additional data (εᵣ most prominently) and the rules for traces/net classes could integrate a simulation option?

(This is really just throwing the idea around…)
