Added new GDK_NO_EXPOSE and GDK_VISIBILITY_NOTIFY events. They are needed

for the TV widget by Alan Cox and by the GtkXmHTML widget.

Only missing with respect to their Xlib counterparts are the
major_code and minor_code fields in the GdkEventNoExpose structure.
Does anyone need them for their code?
