	* app/display/gimpdisplayshell-scale.c: don't emit the "scaled"
	signal from gimp_display_shell_scale_setup(). Emit it explicitely
	from gimp_display_shell_scale_resize() instead.

	* app/display/gimpdisplayshell-scroll.c: call
	gimp_display_shell_scale_setup() after scrolling in order to
	update scrollbars and rulers.

	* app/display/gimpdisplayshell-callbacks.c
	* app/display/gimpdisplayshell-handlers.c: emit the "scaled" signal
	explicitely.

	* app/display/gimpdisplayshell-render.c: minor optimizations.

	* app/display/gimpdisplayshell.c: minor cleanup.
