Hello. I did read this nearly two months old discussion.
It would be nice to have one scenegraph. Such scenegraph
can handle both 3D and 2D. See modern game engines how
they handle 3D and 2D renderings.
GTK already has a some sort of scenegraph built-in, because one
can trace all widgets

Any thoughts on that 3D vs. 2D thing? i.e. it seems like we want to be
able to mix OpenGL and Cairo at will, but it isn't clear to me what that
really means.

The way I see it, you would always have only one item, which just
happens to draw more stuff if zoom level allows it. Or you could have a
single item but with items inside,

Piccolo does have this feature, so it might be interesting to look at
that. Also one of their demos has a lens item, where some items are
only visible if they are intersecting the lens ; not sure how that
demo works, but it seems like

At one zoom level it was showing one set of children, and when zoomed

A number of interesting issues get raised when one talks about scalable
canvases, especially when the complexity of the rendered content changes
with 'zoom level'.
It may be important to distinguish between scaled-canvas-size, and
notional zoom level. For instance, a user with poor vision
