# The setup is as follows:
#  * Each test comes with one <name>.xml GEGL XML and one reference
#    output file in 'reference' called <name>.<ext>, where <ext> is a
#    supported output file type.
#  * The test is run by processing the GEGL XML into an output file in
#    'output', named <name>.<ext>, and then compared with the file in
#    'reference'. If these files are equal, the test is a 'pass'.
