Run pixel tests via automated script.
On origin/master, we only have .ppm format support, so the expected output files would take up a lot of space. Hence, this may not get going until XFA hits with its .png support. Nor is there a good way to diff these; XFA provides this for .png as well. But this will provide at least one automated test to ensure that we've got non-blank output, at least for one trivially simple case.
