Changes since the last public release (1.2.26):
version 1.2.27beta01 [April 12, 2008]
Fixed bug (introduced in libpng-1.0.5h) with handling zero-length
unknown chunks.
Added more information about png_set_keep_unknown_chunks() to the
documetation.
Reject tRNS chunk with out-of-range samples instead of masking off
the invalid high bits as done in since libpng-1.2.19beta5.
version 1.2.27beta02 [April 13, 2008]
Revised documentation about unknown chunk and user chunk handling.
Keep tRNS chunk with out-of-range samples and issue a png_warning().
version 1.2.27beta03 [April 14, 2008]
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.
