That is data. Not every problem is fundamentally about data though — the special case you mention may very well be the whole problem domain. Eg. what percent of data does a compositor work with vs state-holding objects with proper structures like WindowLayoutEngine and the like?

I’m not familiar with compositors, so unfortunately I don’t have a ready answer, only more questions.

What makes a WindowLayoutEngine “a state-holding object with proper structures?” How is it different from “a data tree with proper structure,” except that the former includes methods inside the class instance while the latter relies on functions to operate on the data tree?
