d000fb89c0 [libpng16] Enclosed the new png_get_palette_max
in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED block, and revised pnglibconf.h
and pnglibconf.h.prebuilt accordingly.

3c1f6983c5 [libpng16] Corrected fix for unknown handling in pngtest. This reinstates the
libpng handling of unknown chunks other than vpAg and sTER (including
unsafe-to-copy chunks which were dropped before) and eliminates the
repositioning of vpAg and sTER in pngtest.png by changing pngtest.png
(so the chunks are where libpng would put them).

5d1df4fdf4 [libpng16] Removed png_get_signature() and info_ptr->signature from WRITE-only

4430b91363 [libpng16] Restore info_ptr members that were deleted by the previous
patch; they are needed by png_set_IHDR() for both read and write.  Fix
some ifdefs that caused the contrib/pngminim/ applications to not compile.

b11b31aea2 [libpng16] Changed chunk handler warnings into benign errors, incrementally

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.

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.

29fca0d497 [libpng16] Enabled png_get_sCAL_fixed() if floating point APIs are enabled.
Previously it was disabled whenever internal fixed point arithmetic was
selected, which meant it didn't exist even on systems where FP was available
but not preferred.

88bcdc269b [libpng] Check compression_type parameter in png_get_iCCP and remove spurious
casts. The compression_type parameter is always assigned to, so must
be non-NULL. The cast of the profile length potentially truncated the
value unnecessarily on a 16-bit int system, so the cast of the (byte)
compression type to (int) is specified by ANSI-C anyway.

d58251b47e [libpng15] Reverted previous change; removed png_get_compression_buffer() API.
It is too risky. Exactly how png_ptr->zbuf is used is under control of the
individual chunk implementation and there could easily be significant changes
within a major release.

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.

0a5c9c02fa [devel] Corrected const_png_ in png.h to png_const_ to avoid polluting
the namespace.  Added png_get_current_row_number and
 png_get_current_pass_number for the
 benefit of the user transform callback.
 Added png_process_data_pause and png_process_data_skip for the benefit of
 progressive readers that need to stop data processing or want to optimize
 skipping of unread data (e.g. if the reader marks a chunk to be skipped.)
