For more information about the UTM grid. In Part 1 the prior patches have been rebased to master and cleaned up. Make sure the appropriate grid is shown if

Settings->Configure Marble -> View -> Angle: UTM

is chosen.

In this task the irregular "exception" part at the top of the grid is supposed to get painted. See rows X to V and columns 30-37:
