Rewrites a JSON file to use Python's standard JSON pretty-print format,
so that subsequent runs of rebaseline.py will generate useful diffs
(only the actual checksum differences will show up as diffs, not obscured
by format differences).
Should not modify the JSON contents in any meaningful way.

# We need to add the 'gm' directory, so that we can import gm_json.py within
# that directory. That script allows us to parse the actual-results.json file
# written out by the GM tool.
# Make sure that the 'gm' dir is in the PYTHONPATH, but add it at the *end*
# so any dirs that are already in the PYTHONPATH will be preferred.
#
# This assumes that the 'gm' directory has been checked out as a sibling of
# the 'tools' directory containing this script, which will be the case if
# 'trunk' was checked out as a single unit.
