This would be slightly more efficient if you did this as:

auto markedTexts = MarkedText::collectForDocumentMarkers(renderer(), selectableRange, MarkedText::PaintPhase::Background);
markedTexts.appendVector(MarkedText::collectForHighlights(renderer(), parent()->renderer(), selectableRange, MarkedText::PaintPhase::Background));

though I do like the symmetry in your version.

I wonder if it would make sense at some point to make collectForDocumentMarkers take a functor that does the subdivide rather than allocating the vector then subdividing.

Is there a meaningful efficiency difference? Moving into an empty vector is just setting a pointer?

But yeah, I went for symmetry here.

There is lots of cleanup potential here but I'll try to stay focused on getting stuff out from legacy lines for now. Should be easier to see what to do when everything has been moved out.
