	* app/indicator_area.c
	* app/paths_dialog.c
	* app/tools_cmds.c
	* app/airbrush.c
	* app/airbrush.h

	* tools/pdbgen/enums.pl

	1) Fixed the brushpreview popup problem where it remained onscreen
           if the mouse button was released in another GTK window that accepted
	   mouse events.

	2) Selection to path now works on all types of images (it should have
	   anyway).

	3) Fixed PDB so you can once again use the PDB interfaces to the clone
	   and airbrush tools.

	4) PDB Function to add a path to an image now adds it correctly.

	5) airbrush/paintbrush/clone/eraser/convolve New PDB functions that
           use the options dialogs settings (or sane defaults if option dialog
           not present)

	6) Added PDB functions for Smudge & DodgeBurn tools.

	7) Path stroke command (from the LCP dialog) can now use any of the
	   painting tools (airbrush/paintbrush/clone/eraser/convolve/smudge/
           dodgeburn except ink). Just have the tool selected when you
	   press the stroke button.
