   7 /*  Rework of path-handling (Matthias 04.07.1996 )
   8  * ------------------------------------------------
   9  *   figinsets keep an absolute path to the eps-file.
  10  *   For the user alway a relative path appears
  11  *   (in lyx-file, latex-file and edit-popup).
  12  *   To calculate this relative path the path to the
  13  *   document where the figinset is in is needed.
  14  *   This is done by a reference to the buffer, called
  15  *   figinset::cbuffer. To be up to date the cbuffer
  16  *   is sometimes set to the current buffer
  17  *   bufferlist.current(), when it can be assumed that
  18  *   this operation happens in the current buffer.
  19  *   This is true for InsetFig::Edit(...),
  20  *   InsetFig::InsetFig(...), InsetFig::Read(...),
  21  *   InsetFig::Write and InsetFig::Latex(...).
  22  *   Therefore the bufferlist has to make sure that
  23  *   during these operations bufferlist.current()
  24  *   returns the buffer where the figinsets are in.
  25  *   This made few changes in buffer.C necessary.
  26  *
  27  * The above is not totally valid anymore. (Lgb)
