   This is the inset locking stuff needed for mathed --------------------

   an inset can simple call LockInset in it's edit call and *ONLY* in it's
   edit call.
   Inset::Edit() can only be called by the main lyx module.

   Then the inset may modify the menu's and/or iconbars. 

   Unlocking is either done by LyX or the inset itself with a UnlockInset-call

   During the lock, all button and keyboard events will be modified
   and send to the inset through the following inset-features. Note that
   Inset::InsetUnlock will be called from inside UnlockInset. It is meant
   to contain the code for restoring the menus and things like this.

   
   virtual void InsetButtonPress(int x, int y, int button);
   virtual void InsetButtonRelease(int x, int y, int button);
   virtual void InsetKeyPress(XKeyEvent *ev);
   virtual void InsetMotionNotify(int x, int y, int state);
   virtual void InsetUnlock();

   If a inset wishes any redraw and/or update it just has to call
   UpdateInset(this).
   It's is completly irrelevant, where the inset is. UpdateInset will
   find it in any paragraph in any buffer. 
   Of course the_locking_inset and the insets in the current paragraph/buffer
   are checked first, so no performance problem should occur.
   
   Hope that's ok for the beginning, Alejandro,
   sorry that I needed so much time,

                  Matthias
