Examples changes that were necessary: - loft.py: failed on macos (only) because of (seemingly) over-precise floating-point accuracy assertion. Loosened the tolerance, and expressed it as a multiple of the expected value. > AssertionError: delta=0.002982314711971412 is greater than tolerance=0.001; got=1306.3375467197516, want=1306.3405290344635 - packed_boxes.py: only emit output files when GEN_DOCS is True (mimicking lego.py).
