// .NAME vtkTessellatedBoxSource - Create a polygonal representation of a box
// with a given level of subdivision.
// .SECTION Description
// vtkTessellatedBoxSource creates a axis-aligned box defined by its bounds
// and a level of subdivision. Connectivity is strong: points of the vertices
// and inside the edges are shared between faces. In other words, faces are
// connected. Each face looks like a grid of quads, each quad is composed of
// 2 triangles.
// Given a level of subdivision `l', each edge has `l'+2 points, `l' of them
// are internal edge points, the 2 other ones are the vertices.
// Each face has a total of (`l'+2)*(`l'+2) points, 4 of them are vertices,
// 4*`l' are internal edge points, it remains `l'^2 internal face points.
//
// This source only generate geometry, no DataArrays like normals or texture
// coordinates.
