OK. But non-copper pads (or non-copper layers in normal pads) don't have
"net pad clearance" at all, even when they collide with another pad's items
in the same layer. And because the other clearance values aren't applied to
aperture pads it would be appropriate to say "clearance values are used
only for pads on copper layers".
