	Extracted the CGContextRef creation into a virtual function of
	GdkDrawableImplQuartz; implement get_context() for GdkPixmap and
	GdkWindow

	* gdk/quartz/gdkdrawable-quartz.c
	(gdk_quartz_drawable_get_context): dropped the different
	implementations; forward to the virtual function now
	* gdk/quartz/gdkdrawable-quartz.h: added the virtual function
	* gdk/quartz/gdkpixmap-quartz.c
	(gdk_pixmap_impl_quartz_get_context),
	(gdk_pixmap_impl_quartz_class_init): implemented get_context()
	* gdk/quartz/gdkwindow-quartz.c
	(gdk_window_impl_quartz_get_context),
	(gdk_window_impl_quartz_class_init): implemented get_context()
