The units of a local frame's x and y, east and north of its origin. Up is in metres in both.
meters - Metres on the ground at the origin.
mercatorMeters - EPSG:3857 (Web Mercator) metres, which stretch ground metres by 1/cos(latitude):
the frame of geometry authored in that coordinate system, such as 3D tiles.
Its metres are EPSG:3857's, on the WGS84 equator's radius, which makes them 0.11% longer than the
metres of MapLibre's MercatorCoordinate.
