Gosub Browser Progress, pt46

Now that the components have been pretty much merged, the payout of a modular system starting to pay off. We now have a multitude of browsers based on different toolkits (egui, gtk4, winit) and backend renderers (vello, skia, cairo), with all kind of combinations.

Most of the work at this moment is doing a big cleanup of the codebase to get into a solid foundation, but it's nice to actually see sites being rendered.

For the last 3 weeks, i've been trying to capture a set of websites with the gosub screenshot tool, so we can see progress on what is happening on a weekly basis. I will try to get this online soon.

Also, we are about ready to release a new website.
