We frequently use '-' within the test name or format name and so we encounter confusion as '-' is also used as the field separator. At times this has caused a new test to break an old test because the new test would match one of the old test's target specific reference images. So switch everything over to use '.' between fields (test name, target, format, subtest, etc.).
