Title: Update dompdf_config.inc.php

Should check if constats already exists.

Use case : I'm using zf2 dompdf module and phpoffice/phpexcel, I want to print some excel files and use dompdf wich is loaded with dompdf module. It will load dompdf a second time so I need to check if this constants are already in use.
