* Added information about png_set_options() to the manual.
* Delay calling png_init_filter_functions() until a row with nonzero
filter is found.
* Fixed inconsistent conditional compilation of
png_chunk_unknown_handling() prototype, definition, and usage.
Made it depend on PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.

- updated to 1.6.2:
Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling.
Fixed incorrect warning of excess deflate data. End condition - the
warning would be produced if the end of the deflate stream wasn't read
in the last row. The warning is harmless.
Corrected the test on user transform changes on read. It was in the
png_set of the transform function, but that doesn't matter unless the
transform function changes the rowbuf size, and that is only valid if
transform_info is called.
Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
(Flavio Medeiros).
Corrected length written to uncompressed iTXt chunks (Samuli Suominen).
Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length
written by libpng-1.6.0 and 1.6.1.
Disallow storing sRGB information when the sRGB is not supported.
Merge pngtest.c with libpng-1.7.0

- conflict with libpng12-compat-devel-32bit and libpng15-compat-devel-32bit
- updated to 1.6.1:
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.
