945cb1f9be [libpng16] Issue a png_benign_error() instead of png_warning() about bad 
palette index.

b5d0051dcb [libpng16] Deflate/inflate was reworked to move common zlib calls into single 
functions [rw]util.c.  A new shared keyword check routine was also added
and the 'zbuf' is no longer allocated on progressive read.  It is now
possible to call png_inflate() incrementally.

fcd301daed [libpng16] Changed png_memcpy to C assignment where appropriate. Changed all 
those uses of png_memcpy that were doing a simple assignment to assignments
(all those cases where the thing being copied is a non-array C L-value.)
Added some error checking to png_set_*() routines and removed the
reference to the non-exported function png_memcpy() from example.c. Fixed
the Visual C 64-bit build - it requires jmp_buf to be aligned, but it had
become misaligned.

4f67e40898 [libpng16] Add 'const' to png_structrp arguments of png_set_*() APIs. 
Because these APIs store to the png_info they can take a
 png_const_structrp now that the error routines also accept
 one of these.

5d56786eff [libpng16] Implemented 'restrict' for png_info and png_struct. 
Added new "png_structrp" typedef. Because of the
way libpng works both png_info and png_struct are always accessed via a
single pointer.  This means adding C99 'restrict' to the pointer gives
the compiler some opportunity to optimize the code.  This change allows that.

67ee8cee39 [libpng16] bump version to 1.6.0beta04 2011-12-22 08:34:26 -06:00
John Bowler
40b2603687 [libpng16] Start-up code size improvements, error handler flexibility. These 
changes alter how the tricky allocation of the initial png_struct and png_info
structures are handled. png_info is now handled in pretty much the same
way as everything else, except that the allocations handle NULL return
silently.  png_struct is changed in a similar way on allocation and on
deallocation a 'safety' error handler is put in place (which should never
be required).  The error handler itself is changed to permit mismatches
in the application and libpng error buffer size; however, this means a
silent change to the API to return the jmp_buf if the size doesn't match
the size from the libpng compilation; libpng now allocates the memory and
this may fail.  Overall these changes result in slight code size
reductions; however, this is a reduction in code that is always executed
so is particularly valuable.  Overall on a 64-bit system the libpng DLL
decreases in code size by 1733 bytes.  pngerror.o increases in size by
about 465 bytes because of the new functionality.

751561218f [libpng15] Constant changes for 64-bit compatibility (removal of L suffixes). 
The 16-bit cases still use "L" as we don't have a 16-bit test system.

f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

f70c7d02e9 [devel] Added named value and 'flag' gamma support to png_set_gamma. Made a 
minor change from the previous (unreleased) ABI/API to hide the exact value
used for Macs - it's not a good idea to embed this in the ABI!
