[Documentation] video demo

[RichardFevrier]

Hello 🙂 a video/GIF about the UI/UX on different platforms would be a nice to have. Thanks for all.

Best regards.

@RichardFevrier thanks for your suggestion. Currently the UI looks a bit different than in the image of the demo, because I changed the drawing backend (from NanoVG to Skia) and some things are still not implemented. I will follow your suggestion after this is improved.

In general the framework is in a very rough state and I can't recommend using it for more than a pet project.
