Wishlist: DRC report should display the violation measurement (lp:#1810845)

Original report created by Robert (robee)

The DRC reports show us each error with good information about which 2
elements are in violation, but it would be even better to report the actual
measurements that DRC is seeing.  So if I have 4 mil spacing rules and I
see a 3.98 mil spacing, I know I can ignore it.  This also allows me to set
more restrictive rules to see if I can make changes that would aid
manufacturing or lower the cost.  Finally, I'm one who believes tools can
be wrong, so I'd like to verify that the measurement the tool is seeing is
something that is really a problem.  Knowing the tool calculation will tell
me if DRC is off.
