2e92b4dfa0 [libpng16] Corrected simplified API default gamma for color-mapped output, added 
a flag to change default. In 1.6.0 when the simplified API was used
to produce color-mapped output from an input image with no gamma
information the gamma assumed for the input could be different from
that assumed for non-color-mapped output.  In particular 16-bit depth
input files were assumed to be sRGB encoded, whereas in the 'direct'
case they were assumed to have linear data.  This was an error.  The
fix makes the simplified API treat all input files the same way and
adds a new flag to the png_image::flags member to allow the
application/user to specify that 16-bit files contain sRGB data
rather than the default linear.
Fixed bugs in the pngpixel and makepng test programs.

808ea281a4 [libpng17] Corrected Android builds and corrected libpng.vers with symbol 
prefixing. This adds an API to set optimization options externally,
providing an alternative and general solution for the non-portable
run-time tests used by the ARM Neon code.  It also makes those tests
compile and link on Android.  The order of settings vs options in
pnglibconf.h is reversed to allow settings to depend on options and
options can now set (or override) the defaults for settings.

ec89aefb44 [libpng17] Changed user chunk callback API to respect global and per chunk 
defaults.  Previously a return of 0 from a user chunk callback would result in
the chunk being saved (if this was safe, even if the chunk was unsafe-to-copy);
this change respects the defaults set by the application, so unknown chunks
can be discarded by default and known-safe ones preserved.

6152dbd424 [libpng17] Fixed bug introduced in libpng-1.6.0beta28 that causes libpng to 
handle chunks even when they have been tagged PNG_HANDLE_CHUNK_NEVER.
Also fixed two typos (SUPPOPRTED should be SUPPORTED) in pngrutil.c

f15a5006c8 [libpng17] Removed cc -E workround, corrected png_get_palette_max API. Tested 
on SUN OS cc 5.9, which demonstrates the tokenization problem previously
avoided by using /lib/cpp.  Since all .dfn output is now protected
in double quotes unless it is to be macro substituted the fix should work
everywhere.
