a671f8baea [libpng17] Quieted Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, 
pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
would only work with iTXt chunks with length 255 or less.

13d83c6948 [libpng17] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the 
compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated.

7a35bcac1a [libpng17] Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler 
(Bug report by Viktor Szaka'ts).

673ae608ab [libpng17] Transformed rewrite: changed row_info, added checks. This introduces an 
internal struct (png_transform_control) to replace row_info and uses
    that to implement affirms correctly.  The change also adds checks on
    the rowbytes calculation and additional checks on most transform
    implementations.
Added png_uint_16 range checking, pngvalid tRNS, fixed png_uint_16:
    review of previous checks, removal of some where SAFE. pngvalid: add
    testing of tRNS for better code coverage pngvalid: correct rgb-to-gray
    error calculations. Code coverage is still incomplete: see /*UNTESTED*/
    in pngrtran.c

53097f5bbb [libpng17] Check (png_uint_16) casts for overflow. Also removed png_muldiv_warn, 
added RELEASE/!RELEASE convenience macros. png_muldiv_warn was used in
only one place, and the overflow condition is a genuine warning not
an internal error.  Four macros allow code or function parameters to be
condition on RELEASE (or not) builds and tidy up the #ifdef handling of
functions.

John Bowler
36562c1032 [libpng17] Improved some overflow handling. PNG_RELEASE_BUILD replaces tests 
where the code depended on the build base type and can be defined on
the command line, allowing testing in beta builds.  Overflows previously
handled by png_warning in png.c have been changed to use new
macros/affirm functions so that beta builds will abort on overflow and
release builds will quietly ignore it.  This avoids release builds
producing warnings that are of no use to end users.

82fa6aed0e [libpng17] Added byte, short and other overflow checking 
Added 'assert' based overflow checking for debug builds for char
and short assignments. Simply ignore the error in release builds
(a truncated value will be used without warning). Controlled by
PNG_RANGE_CHECK_SUPPORTED.
