Jay Berkenbilt dc9b7287cd Top-level json: write incrementally 
This commit just changes the order in which fields are written to the
json without changing their content. All the json files in the test
suite were modified with this script to ensure that we didn't get any
changes other than ordering.

----------
#!/usr/bin/env python3
import json
import sys

def json_dumps(data):
    return json.dumps(data, ensure_ascii=False,
                      indent=2, separators=(',', ': '))

for filename in sys.argv[1:]:
    with open(filename, 'r') as f:
        data = json.loads(f.read())
    newdata = {}

# manual-appearances was created by hand-coding appearance streams
# with graphics that make it easy to test matrix calculations. The
# result of flattening the annotations was compared visually with
# okular. Some PDF viewers don't actually display the original version
# correctly. The pages are as follows:
# - page 1: normal
# - page 2: rotate 90 with /F 20 (NoRotate)
# - page 3: non-trivial matrix
# - page 4: non-trivial matrix, rotate
# - page 5: rotate 180 with /F 20
# - page 6: rotate 90, /F 20, non-trivial matrix
# - page 7: flags: top is print, middle is screen, bottom is hidden
# - page 8: rotate 270 with /F 20
# - page 9: normal -- available for additional testing
#
# form-filled-by-acrobat was filled in using the Acrobat Reader

# need-appearances.pdf is based on field-types.pdf with manual edits

# - field-types.pdf has /NeedAppearances true
# - text1: blank -> abc

# - list1: blank -> five
# - combolist1: blank -> pi
# - drop1: blank -> elephant
