Made sRGB check numbers consistent.
Use parentheses more consistently in "#if defined(MACRO)" tests.
Reenabled code to allow zero length PLTE chunks for MNG.
Fixed ALIGNED_MEMORY support.
Avoid a possible memory leak in contrib/gregbook/readpng.c
Better documentation of unknown handling API interactions.
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.
