Jupyter canvas

Closes #176

I'm going to leave this open until I've updated pygfx, so I can make sure that it works well for pygfx too.

Can you tell me a little bit about how this works if someone has multiple cells with rendered scenes in each cell?

Good question. Each cell would probably create a new canvas with a new renderer. So the device would be shared (we should probably make that so), but each canvas comes with its own pipeline(s). I should make a notebook with multiple cells to get a better feel. Will do when we can use pygfx.

BTW: you may see in the screenshots that the colors are a bit off. This has been fixed too by using the appopriate texture format.

[Korijn]

What happens if you leave out the animation loop and just render once? Does that work?

[almarklein]

Yes. Then a redraw is only requested when the canvas is resized (in the browser) like with normal windows.
