	offset_[xy].

	* app/display/gimpdisplayshell-scroll.[ch]
	(gimp_display_shell_scroll_clamp_offsets)
	(gimp_display_shell_get_scaled_image_viewport_offset): Adjust
	accordingly to preserve current behaviour.

	(gimp_display_shell_get_disp_offset): New function to get the old
	disp_[xy]offset based on the new offset_[xy].

	(gimp_display_shell_get_render_start_offset): New function to get
	th old offset_[xy] based on the new offset_[xy].

	* app/display/gimpdisplayshell-draw.c
	* app/display/gimpdisplayshell-scale.c
	* app/display/gimpdisplayshell-render.c: Get rid of
	disp_[xy]offset and use
	gimp_display_shell_get_render_start_offset() and
	gimp_display_shell_get_disp_offset() instead.
