Changes since the last public release (1.6.20):
Version 1.6.21beta01 [December 11, 2015]
Fixed syntax "$(command)" in tests/pngstest that some shells other than
bash could not parse (Bug report by Nelson Beebe). Use `command` instead.
Version 1.6.21beta02 [December 14, 2015]
Moved png_check_keyword() from pngwutil.c to pngset.c
Removed LE/BE dependencies in pngvalid, to 'fix' the current problem
in the BigEndian tests by not testing it, making the BE code the same

Fixes to pngvalid for various reduced build configurations (eliminate unused
statics) and a fix for the case in rgb_to_gray when the digitize option
reduces graylo to 0, producing a large error.
Version 1.6.21beta03 [December 18, 2015]
Widened the 'limit' check on the internally calculated error limits in
the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error
checks) and changed the check to only operate in non-release builds

This changes pngvalid to use BE random numbers; this used to produce
errors but these should not be fixed as a result of the previous changes.
Version 1.6.21rc01 [January 4, 2016]
In projects/vstudio, combined readme.txt and WARNING into README.txt
Version 1.6.21rc02 [January 7, 2016]
Relocated assert() in contrib/tools/pngfix.c, bug found by American
Fuzzy Lop, reported by Brian Carpenter.
Marked 'limit' UNUSED in transform_range_check(). This only affects
release builds.
Version 1.6.21rc03 [January 13, 2016]
Worked around a false-positive Coverity issue in pngvalid.c.
