Cauldron2D.Parallax.Strip (Cauldron2D v0.2.2)

A cell function over authored tiles, wrapping in one or both directions.

rows = Cauldron2D.Parallax.Strip.legend(["..#..", "#####"], %{"#" => :brick, "." => :void})
Cauldron2D.Parallax.Strip.cells(rows, wrap: :x)

Row 0 of the tiles is tile row 0 of the layer. A coordinate outside the tiles on an axis that does not wrap is :void.
