ORCA2 Grid
----------

This example demonstrates how to render a curvilinear grid.

📋 Summary
^^^^^^^^^^

Creates a mesh from 2-D latitude and longitude curvilinear cell bounds.

The resulting mesh contains quad cells.

It uses an ORCA2 global ocean with tri-polar model grid with sea water
potential temperature data. The data targets the mesh faces/cells.

Note that, a threshold is also applied to remove land ``NaN`` cells, and a
Natural Earth base layer is rendered along with Natural Earth coastlines.
