 The raster tests can be run and the pixel results compared to known good (golden) images generated from previous runs.  To generate golden images, make sure that the tests are rendering as expected, and then run with --save-images.  This will generate .ppm files for all of the tests.  Create a directory called "golden" and "mv *.ppm golden".  When new tests are added to render_tests additional golden images will need to be generated for the new tests.
