59ae38984f [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.

f3728100d9 [libpng16] 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.

09a5ca72ac [libpng16] Allow run-time ARM NEON checking to be disabled. A new configure
option:
    --enable-arm-neon=always will stop the run-time checks. New checks
    within arm/arm_init.c will cause the code not to be compiled unless
    __ARM_NEON__ is set. This should make it fail safe (if someone asks
    for it on then the build will fail if it can't be done.)
Fixed ALIGNED_MEMORY support.

0695fcd834 [libpng16] 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.
