I did not study the code in detail but should some of these be par_iter() from rayon or depending on the workload par_iter with_min_length? |

This seems pretty harmless. Without measurement, I'm not sure these kind of micro-optimizations make sense though. Most of the collecting is probably happening in layout itself which runs more often and deals with more nodes than layout queries. I think a good thing for these kind of optimizations in the future is some actual measurement.

Profiling a speedometer run showed significant time spent in some layout function in vector allocations. The main change is to switch the result of
query_box_areas()from a Vec to and iterator.Testing: refactoring with no expected test changes
