parameter queries should mirror DG interior weighting scheme
The DG operator queries the paramterizations at each side of an intersection. However, since parameterization queries are based on global coordinates in Dorie, this results in querying the same values twice.
Proposal: Add small offsets to both parameter queries to ensure that two parameterizations can be queried. This, however, should only make a difference if the grid intersections coincide with the parameter field intersections.
