regular-2d-grid
Represents a regularly-sampled two-dimensional grid (i.e., image) and data attached to the cells and vertices.
The grid implements spatial properties including a coordinate reference system and bounding box in world coordinates.
The grid origin is defined in three dimensions, along with rotation (defined per the Rotation schema component).
The size of the grid is specified in cells (see size), each of which has the same rectangular dimensions (see cell_size) throughout the grid.
Fields cell_attributes and vertex_attributes accept a variety of scalar values (see One of Attribute component), attached to either the cells (of length grid_size_x * grid_size_y) or vertices (of length [grid_size_x + 1] * [grid_size_y + 1]).
