* 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.
