   5 /*  Rework of path-handling (Matthias 04.07.1996 )
   6  * ------------------------------------------------
   7  *   figinsets keep an absolute path to the eps-file.
   8  *   For the user alway a relative path appears
   9  *   (in lyx-file, latex-file and edit-popup).
  10  *   To calculate this relative path the path to the
  11  *   document where the figinset is in is needed.
  12  *   This is done by a reference to the buffer, called
  13  *   figinset::cbuffer. To be up to date the cbuffer
  14  *   is sometimes set to the current buffer
  15  *   bufferlist.current(), when it can be assumed that
  16  *   this operation happens in the current buffer.
  17  *   This is true for InsetFig::Edit(...),
  18  *   InsetFig::InsetFig(...), InsetFig::Read(...),
  19  *   InsetFig::Write and InsetFig::Latex(...).
  20  *   Therefore the bufferlist has to make sure that
  21  *   during these operations bufferlist.current()
  22  *   returns the buffer where the figinsets are in.
  23  *   This made few changes in buffer.C necessary.
  24  *
  25  * The above is not totally valid anymore. (Lgb)
