[tex-live] General test suite for TeX-Live

[R. Padraic Springuel]

As an example of using imagemagik to compare pdf outputs, people might want to take a look at the gregorio-test repository on GitHub (https://github.com/gregorio-project/gregorio-test). While our infrastructure is bash based, we use imagemagik to check the output from using our package against a previously produced known good model.  Furthermore, by specifying the paper size and a font which is provided locally in the test repository, we're able to do this across both Mac and Linux systems running in both the US and Europe.
