A tibble of the point coordinates of x.
This table contains three columns (x, y and fid) and as many rows as
there are points. In case x is a polygon, the last point of each
distinct feature is a duplicate of its first point. In case x has
the type 'grid', all layers are summarised into one tibble, as several
layers must have the same extent and resolution, so that each point occurrs
in each layer, merely with a different, layer-specific value.
