  We have been experiencing problems with printing tables where
one of the cells contains a raster image  (or any other inset
that produces PostScript output directly).
  Rather than printing the raster, the final document appears
with the _text_ of the PostScript instead.

  What appears to be happening is that table uses a troff
diversion to hold the body of each row, to ensure that page
breaks can occur when required.  This means that the troff is
processed twice - once for the diversion, and again when the
macro is executed.
  The PostScript is protected by a single level of transparency,
which is stripped off during the diversion.  Hence, when the macro
is executed, the PostScript is no longer passed through unchanged,
and gets printed like everything else.

  This is all using DITroff.  Groff does what you would expect
(even though it technically shouldn't).

  Any ideas?  (Other than 'use groff'!)
