[luatex] Creating pdf_dest nodes

[Andreas Matthias]

In the following example I tried to create two pdf destinations,
the first one using /pdfextension, and the second one using the
node library. However only the first one is available, while
the second one is missing. What am I doing wrong?

\pdfvariable compresslevel = 0

\pdfextension dest name {aaa} xyz zoom 2000

\directlua{
  d = node.new('whatsit', 'pdf_dest')
  d.width = 100*65536
  d.height = 100*65536
  d.depth = 0
  d.named_id = true
  d.dest_id = 'bbb'
  d.dest_type = 0
  d.xyz_zoom = 2
  node.write(d)
}
\bye
