	* app/tools/gimptool.[ch]
	* app/tools/tool_manager.[ch]: add "gboolean proximity" parameter
	to GimpTool::oper_update() in order to emphasize its importance
	and to avoid peeking around in the GimpDisplayShell struct.

	* app/tools/gimpbycolorselecttool.c
	* app/tools/gimpclonetool.c
	* app/tools/gimpcolorpickertool.c
	* app/tools/gimpcolortool.c

	* app/tools/gimprectangletool.[ch]
	* app/tools/gimpselectiontool.c
	* app/tools/gimptransformtool.c
	* app/tools/gimpvectortool.c: changed accordingly. Got rid of
	quite some "display/gimpdisplayshell.h" includes.

	* app/display/gimpdisplayshell-callbacks.c
	(gimp_display_shell_canvas_tool_events): pass shell->proximity to
	tool_manager_oper_update_active().
