vendor patch doesn't pass regression tests. upstream patch is better and passes the tests. for hardy, probably need to backport crasher fixes http://cvs.savannah.gnu.org/viewvc/OpenEXR/IlmImf/ImfHuf.cpp?root=openexr&r1=1.6&r2=1.7 http://cvs.savannah.gnu.org/viewvc/OpenEXR/IlmImf/ImfHuf.cpp?root=openexr&r1=1.7&r2=1.8
