GDK should now be constified as far as possible without breaking source compatibility. Includes some minor cleanup like indentation and s/nfoo/n_foo/ (bug #508544). * gdk/gdkdisplay.c * gdk/gdkdraw.c * gdk/gdkevents.c * gdk/gdkpango.c * gdk/gdkregion-generic.c * gdk/gdkrgb.c * gdk/directfb/gdkdisplay-directfb.c * gdk/directfb/gdkwindow-directfb.c * gdk/quartz/gdkdisplay-quartz.c * gdk/quartz/gdkwindow-quartz.c * gdk/win32/gdkdisplay-win32.c * gdk/win32/gdkwindow-win32.c * gdk/x11/gdkdisplay-x11.c * gdk/x11/gdkwindow-x11.c: changed accordingly. svn path=/trunk/; revision=19372
