These fixes attend to most of the errors revealed in pngvalid, however doing the gamma work twice results in inaccuracies that can't be easily fixed. There is now a warning in the code if this is going to happen.

It is too risky. Exactly how png_ptr->zbuf is used is under control of the individual chunk implementation and there could easily be significant changes within a major release.

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.

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.

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.
