version 1.2.28 [April 30, 2008]
Fixed bug (introduced in libpng-1.0.6) with handling zero-length
unknown chunks.
Added more information about png_set_keep_unknown_chunks() to the
documetation.
Revised documentation about unknown chunk and user chunk handling.
Issue a png_warning when reading a tRNS chunk with out-of-range samples.
Added check for NULL ptr in TURBOC version of png_free_default().
Removed several unnecessary checks for NULL before calling png_free().
Revised png_set_tRNS() so that calling it twice removes and invalidates
the previous call.
Revised pngtest to check for out-of-range tRNS samples.
Added AC_LIBTOOL_WIN32_DLL to configure.ac
Added MAINTEINERCLEANFILES variable to Makefile.am
Avoid changing color_type from GRAY to RGB by
png_set_expand_gray_1_2_4_to_8().

Removed a stray object file from contrib/gregbook
