Overview

Simple structure to make it more readable to build the UV mapping array for Sketchup::Face#position_material.

Examples:

mapping = UVMapping.new
mapping.add(points[0], UV.new(0, 0))
mapping.add(points[1], UV.new(1, 0))
mapping.add(points[2], UV.new(1, 1))
mapping.add(points[3], UV.new(0, 1))
face.position_material(material, mapping.to_a, true)

  # TODO: Remove this? This object doesn't really behave like an array.
  #   It was added as an attempt to avoid calling .to_a when passing on to
