Used to compute the valid vertices (corners) of an image. The valid verticies are defined as a 4 point polygon. Inside the polygon are valid sampled pixels outside are nulls. Results are saved to a keyword list.

Name of the keyword list is the image_file with"_vertices.kwl" appended. So if image = "foo.tif" then results file = "foo_vertices.kwl".
