Integration with asyn/three-d

[bryce-happel-walton]

This has been brought up before and I made an issue aswell, but the issue was closed with no useful information added.

Has anyone gotten three-d to work with Skia, while using their RenderTarget? I can get it to work just as expected under FemtoVG, but this is claimed to be a bug with FemtoVG. Skia completely breaks apart. I've hacked together examples from both Slint and three-d, but nothing works as expected.
