Finally enable compositing, 3d-transforms, etc. for SVG.
All the preparatory work is done and LBSE has enough functionality to support it.

Hi, I tested 253054@main. But, your tiger doesn't animate. Is this expected? https://ibb.co/mcSnFZP

Thanks Fujji for the early testing. Yes it is expected -- there's still stuff missing to make the demos work. I will let you know when you can repeat the testing :-)

Oh, I mixed this up, thought you were talking about the vibrant tiger example. The one from 2019 in the reveal.js presentation should work -- did you click on "Welcome to the future" to trigger the animation?

NOTE: You'll notice that the tiger SVG is clipped -- that's a bug in the actual html/svg file, due to missing viewport clipping in earlier LBSE versions. To see the unclipped tiger, you need to manually enlarge the viewport in the svg document fragment.

Oh, I didn't click. It works! You did a great job!

Thanks Fujii, still LBSE is not ready yet for production. I will soon create GitHub issues on https://github.com/nikolaszimmermann/WebKitIgalia/issues, to track what's still missing in LBSE -- better than tickin' off items on my personal, invisible TODO list :-)
