	* app/display/gimpdisplayshell-transform.[ch]: renamed
	transform_coords() to transform_coordinate(); same for the
	untransform variant. Added new functions transform_points() and
	transform_coords() that work on arrays.

	* app/display/gimpdisplayshell-autoscroll.c
	* app/display/gimpdisplayshell-callbacks.c: changed accordingly.

	* app/tools/gimpdrawtool.c (gimp_draw_tool_draw_lines)
	(gimp_draw_tool_draw_strokes): use the new transform functions.
