   Changes since 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
     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.
