    * gimpdrawable.c: enabled the (commented out) signal
    * app/layers_dialog.c: connect to the "invalidate_preview"
      signal to catch changes that need to be shown in the layer
      previews. Synthetize an expose event when a layer changes.
      Expose events are optimzed away by GTK+ if the widget is not
      visible. Therefore, previews not visible in the layers_dialog
      are not redrawn when they invalidate. Later the preview gets
      validated by the image_preview in lc_dialog but is never
      propagated to the layer_pixmap. We work around this by using an
      additional flag "layer_pixmap_valid" so that the pixmap gets
      updated once the preview scrolls into sight.
      Fixes bugs #10549, #10300 and #8787.
