* Starting to factor out attribute accumulation into its own file * Continuing to factor out attribute accumulation * Reduce duplicate code * Plumbing the accumulate-attribute option around * Call the attribute accumulator * Test that accumulation works * Add missing #includes * Don't sort within individual multiplier clusters Doing so throws off the spatial distribution of the low zooms * Docs and changelog * Add comments
