8be28e3eb6 [libpng15] Optimized png_combine_row() when rows are aligned This gains a 
small percentage for 16-bit and 32-bit pixels in the typical case where the
output row buffers are appropriately aligned. The optimization was not
previously possible because the png_struct buffer was always misaligned.

ac8375d000 [libpng15] Align png_struct::row_buf - previously it was always unaligned, 
caused by a bug in the code that attempted to align it; the code needs to
subtract one from the pointer to take account of the filter byte prepended to
each row.

65c0339b5c [libpng15] Speed up png_combine_row() for interlaced images. This reduces the 
generality of the code, allowing it to be optimized for Adam7 interlace.  The
masks passed to png_combine_row() are now generated internally, avoiding
some code duplication and localizing the interlace handling somewhat.

4daae30174 [libpng15] #ifdef out png_progressive_combine_row() when interlacing is

8e25a61277 [libpng15]` Revised test-pngtest.sh to report FAIL when pngtest fails. 
Added "--strict" option to pngtest, to report FAIL when the failure is
only because the resulting valid files are different.

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.

John Bowler
f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.
