public void invalidate ()
This function starts or renews a short low-priority timeout.
When the timeout expires, the GimpPreview:GimpPreview:invalidated signal is emitted which will usually cause the
this to be updated.
This function does nothing unless the "Preview" button is checked.
During the emission of the signal a busy cursor is set on the toplevel window containing the this and on the preview area itself.
