	* gdk/quartz/gdkdrawable-quartz.c: some whitespace and indentation
	cleanup.

	(gdk_quartz_draw_rectangle)
	(gdk_quartz_draw_arc)
	(gdk_quartz_draw_polygon)
	(gdk_quartz_draw_points): for pixel-prefect drawing, stroked
	coordinates need to go through pixel centers, while filled ones
	need to go along pixel boundaries. Moved +0.5 adjusting to the
	if(!filled) branches and added/removed some adjustments where they
	were wrong.
