Carl noticed that we were not setting the /Interpolate flag shortly
before 1.6 was released. I wrote a patch to fix this however there
were some issues. Ghostscript, acroread, and poppler did not render the
filter-bilinear-extents test the same. Carl suggested we revisit this
after 1.6 but I never did get around to finishing it.
