"""Visual that displays a cube or cuboid
Parameters
----------
size : float or tuple
The size of the cuboid. A float gives a cube, whereas tuples may
specify the size of each axis (x, y, z) independently.
vertex_colors : ndarray
Same as for `MeshVisual` class. See `create_cube` for vertex ordering.
face_colors : ndarray
Same as for `MeshVisual` class. See `create_cube` for vertex ordering.
color : Color
The `Color` to use when drawing the cube faces.
edge_color : tuple or Color
The `Color` to use when drawing the cube edges. If `None`, then no
cube edges are drawn.
