With quick testing, without looking into the source, 0.000001 works,
0.0000009 will be changed to 0.000001 and 0.0000001 will be changed to 0.

>From the usability point of view this is, well, I don't have to say. In the
GUI it would be relatively easy to add "inherit" and "use value" options
instead of just using the values in non-intuitive way which has to be
explained with extra text in every place and which leads to this kind of
odd situations where a user can even by accident send buggy files to a
manufacturer (I think it happened to me once!). But I guess it would be a
compatibility issue in the board file level.
