Add simple tutorial for creating custom shapes

[LucianoSaldivia]

I've been doing research and i can't find any step-by-step guide on how to do this, either with an SVG editor nor "programatically". I just find people discussing that here, but no explanation on HOW to do it.
I'd appreciate any tutorial on this, even if it's a youtube link on the documentation explaining how to make a trapezoid 2 to 1 MUX.

I made a video tutorial on this a few years ago. Here ya go: https://youtu.be/SwlBRyOWR3E?si=9e-wUriJIPqohZEu

Wow that was very helpful.
Also the comment from unkebunktebusal9023 was helpful as well.

I think this should be added to the documentation, until something more official comes out.
Thanks a lot @TheWildJarvi.
