Another case where we expect the 'current dictionary' to be writeablePDF_gstate
after a gsave (q) operation. If we don't do a 'gput' in order to make
a writeable copy of nodict and make it current then we get an
invalidaccess error.
Ideally we would like to get rid of nodict, but we still use it for a
lot of PDF interpreter non-gstate related stuff, and we probably
always will, so just do a dummy gput for now.
