vtkProjectedTexture - assign texture coordinates for a projected texture

Description:

vtkProjectedTexture assigns texture coordinates to a dataset as if the texture was projected from a slide projected located somewhere in the scene. Methods are provided to position the projector and aim it at a location, to set the width of the projector's frustum, and to set the range of texture coordinates assigned to the dataset. Objects in the scene that appear behind the projector are also assigned texture coordinates; the projected image is left-right and top-bottom flipped, much as a lens' focus flips the rays of light that pass through it. A warning is issued if a point in the dataset falls at the focus of the projector.
