New upstream release
o SVN snapshot rev 8187
o CJK patches from Koji Otani to fix several issues with CJK text
(should fix http://bugs.ghostscript.com/show_bug.cgi?id=689304).
These patches were also applied to ESP Ghostscript and having them
in Gutsy's GPL GS will avoide regressions against Feisty's ESP GS.
o Minor bug fixes from upstream.
