520803d57e [libpng16] Removed non-working ICC profile support code. There was too much 
code for too little gain; implementing full ICC color correction is maybe
desireable but is left up to applications.

John Bowler
f8dfd123e2 [libpng16] Changed ICC profile support to allow use of an external color 
management system (CMS). In practice it is not possible to obtain cHRM
information reliably using just the end-point tags because they do not exist
in the vast majority of profiles.  Instead it is necessary to run the endpoints
through the ICC colorimetric intent transform (as described in the v4
spec).  Since this is likely to be too much code inside libpng for too
little gain (it implies a fairly complete CMS implementation) the code
has been changed to allow an external CMS to be used.  This code is
temporarily disabled until a suitable set of test cases using one or more
external CMS implementations have been implemented.

b98681b49a [libpng16] Improved ICC profile handling including cHRM chunk generation and 
fixed Cygwin+MSVC build errors. The ICC profile handling now includes more
checking.  Several errors that caused rejection of the profile are now
handled with a warning in such a way that the invalid profiles will be
read by default in release (but not pre-RC) builds but will not be
written by default.  The easy part of handling a cHRM chunk is written,
where the ICC profile contains the required data.  The more difficult
part plus guessing a gAMA value requires code to pass selected RGB values
through the profile.

e9567514dd [libpng16] Unknown handling fixes and clean up. This adds more correct option 
control of the unknown handling, corrects the pre-existing bug where
the per-chunk 'keep' setting is ignored and makes it possible to skip
IDAT chunks in the sequential reader (broken in earlier 1.6 versions).
There is a new test program, test-unknown.c, which is a work in progress
(not currently part of the test suite).  Comments in the header files now
explain how the unknown handling works.

96b917056d [libpng16] Revised png_set_keep_unknown_chunks() so num_chunks < 0 means 
ignore all unknown chunks and all known chunks except for IHDR, PLTE, tRNS,
IDAT, and IEND.  Previously it only meant ignore all unknown chunks, the
same as num_chunks == 0. Revised png_image_skip_unused_chunks() to
provide a list of chunks to be processed instead of a list of chunks to
ignore.  Revised contrib/gregbook/readpng2.c accordingly.

b45416921b [libpng16] Removed need for -Wno-cast-align with clang. clang correctly warns 
on alignment increasing pointer casts when -Wcast-align is passed. This
fixes the cases clang warns about either (pngread.c) by eliminating the
casts from png_bytep to png_uint_16p or, for pngrutil.c where the cast
is previously verified or pngstest.c where it is OK by introducing new
png_aligncast macros to do the cast in a way that clang accepts.

possible to call png_inflate() incrementally.

Further changes will be made to make ICC profile handling more secure.

can be disabled with the --slow option.

bce7988230 [libpng16] Fixed fixed/float API export conditionals. 1) If FIXED_POINT or 
FLOATING_POINT options were switched off, png.h ended up with lone ';'
    characters.  This is not valid ANSI-C outside a function.  The ';'
    characters have been moved inside the definition of PNG_FP_EXPORT and
    PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration
    of the corresponding functions were completely omitted, even though some
    of them are still used internally.  The result is still valid, but
    produces warnings from gcc with some warning options (including -Wall). The
    fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION
    when png.h is included from pngpriv.h.
