/* Session-managment stuff Copyright (C) 1998 Sven Neumann <sven@gimp.org>
I include a short description here on what is done and what problems
are left:
Since everything saved in sessionrc changes often (with each session?)
the whole file is rewritten each time the gimp exits. I don't see any
use in implementing a more flexible scheme like it is used for gimprc.
Right now session-managment is limited to window geometry. Restoring
openend images is planned, but I'm still not sure how to deal with dirty
images.
There is a problem with the offset introduced by the window-manager adding
decorations to the windows. This is annoying and should be fixed somehow.
( Update: I was promised that this will be fixed in gtk. )
Dialogs are now reopened if the gimp is called with the command-line-option
--restore-session or if the related entry is set in gimprc.
Probably there should alternatively be a list of dialogs in the preferences
that should always be opened on start-up.
Please point me into the right direction to make this work with Gnome-SM.
