These days, the needs of web engines are easily as complex as those of
complex games: between <canvas>/2d, css, and svg, there's plenty of
ways that a web page can be a complex 2d game :-) Then throw fonts
into the mix.

I can't speak for Calligra but I would guess it has or will have the
same concerns, although perhaps it's a bit less performance critical
since there is no animated content.

While a scene graph is a great approach to cover simple enough needs,
I would be surprised if it could cover such advanced, yet important
and frequent, use cases.
