/*
  The following turns on code that tries to place data on the
  clipboard on demand rather than blindly. The idea was that we place
  data on clipboard in RTF format only, cache the document state, and
  indicate that we can provide other formats if required.

  The main advantage, obviously, is being able to provide data for the
  clipboard in a myriad of formats, but without taking up system
  resources.

  At present this code is turned off, since we currently only put on
  the clipboard RTF and text and the latter is quite undemading as far
  as resources go. When we add more export formats, such as AW native,
  this line should be uncommented.
