/*
* figinset.C - part of LyX project
*/
/* Rework of path-handling (Matthias 04.07.1996 )
* ------------------------------------------------
* figinsets keep an absolute path to the eps-file.
* For the user alway a relative path appears
* (in lyx-file, latex-file and edit-popup).
* To calculate this relative path the path to the
* document where the figinset is in is needed.
* This is done by a reference to the buffer, called
* figinset::cbuffer. To be up to date the cbuffer
* is sometimes set to the current buffer
* bufferlist.current(), when it can be assumed that
* this operation happens in the current buffer.
* This is true for InsetFig::Edit(...),
* InsetFig::InsetFig(...), InsetFig::Read(...),
* InsetFig::Write and InsetFig::Latex(...).
* Therefore the bufferlist has to make sure that
* during these operations bufferlist.current()
* returns the buffer where the figinsets are in.
* This made few changes in buffer.C necessary.
*
* The above is not totally valid anymore. (Lgb)
