The hardest part is naming things, I ended up with duplicate DU:s (same DU cases) for the sizing called ColumnWidth and RowHeight as I had trouble coming up with a good name fitting both usages. GridSize was probably my best alternative but it reads like it applies to the Grid as a whole, I would be ok with changing to that though.
This implements what was discussed in #365
