jean-pierre charras 91dfa79a67 Plot pad outlines on Fab files: fix many issues. 
Depending on plotter type and pad type, the plotted shapes were not always the outlines,
but a outline inside the pad shape (due to legacy reasons).
In many cases the plotted shape was in fact incorrect.
(only noticeable for very small pads)
Now the actual pad outlines are plotted without modification.
Fixes #11484
