    gdk: master clock: hook ourselves to the paint signal
    
    We're currently hooked to the "update" signal of the FrameClock. When
    embedding Clutter inside GTK+ we want to have the layout phase of GTK+
    to notify us the size of our stage.
    
    This patch change to FrameClock signal we're listening to, to the
    "paint" signal to make sure we've received the layout information from
    GTK+, before painting. Otherwise we paint with a delay of one frame.
