	Fixes #543868: GdkPixmap is upside down on quartz

	* gdk/quartz/gdkdrawable-quartz.c (gdk_quartz_draw_drawable): flip the
	coordinate space from GTK+ orientation to CoreGraphics orientation
	before calling CoreGraphics code
	* gdk/quartz/gdkgc-quartz.c (gdk_quartz_draw_tiled_pattern): drop the
	coordinate space flipping (we always get it right, now)
	* gdk/quartz/gdkpixmap-quartz.c
	(gdk_pixmap_impl_quartz_get_context): flip the coordinate space when
	creating the CGContextRef
