Due to differences in rendering between platforms (mainly antialiasing), we had to lower the rigor with which we test our EPS handling. Instead of making the test fail if the rendered image does not exactly match, we now only fail if the images are grossly divergent.
We now have a test harness for EPS files. Two variants were created one for the default scale=1 and one where scale=2. These two tests are run against two different EPS files, one with zero for the start of the bounding box and one where this is not the case. PNG test renders are used to make sure the output match what we expect. Lastly the sample EPS files were generated using the included create_eps.gnuplot file and the gnuplot program on a Mac.
