Log Message:
Update to 1.5.5

Reset reduce_to_gray and it_is_opaque flags prior to processing each image.
Enable removal of safe-to-copy chunks that are being handled as unknown
Added 262 to the length of uncompressed data when calculating
required_window_size, to account for zlib/deflate implementation.
Added "-bit_depth n" to the help screen.
Call png_set_packing() when increasing bit_depth to 2 or 4.
Added warning about not overwriting an existing tRNS chunk.
Reduced the memory usage
Write 500K IDAT chunks even when system libpng is being used.
Ignore all-zero gAMA and cHRM chunks, with a warning.
Added "-loco" option (writes MNG files with filter_method 64)
"-dir" and "-ext" options are no longer mutually exclusive, e.g.:
pngcrush -loco -dir Crushed -ext .mng *.png
Added "-iccp" option
Increased the zlib memory level to 9, which improves compression
Enabled the "-max max_idat_size" option, even when max_idat_size
exceeds the default 1/2 megabyte size.
Added missing "png_ptr" argument to png_error() call
Revised the "-help" output slightly and improved the "-version" output.
The "-already[_crushed]" option is now ignored if the "-force" option
is present or if chunks are being added, deleted, or modified.
Improved "things_have_changed" behavior (now, when set in a particular file, it is not set for all remaining files)
