         That has been implemented in Xpdf for YEARS.  I'd like to

         That is part of the latest patches that you have from Xpdf.

         That's implemented for Splash, but may not be for other backends.

         I believe that is in the latest patches from Xpdf.

are MAJOR pieces of work that Derek hasn't undertaken yet.
