Fixes to ImageObserver calls

Hi, 
Here's for review. This, I hope, should fix some bugs related to
ImageObserver. On doing a Graphics.drawImage() the observer gets too
many imageUpdate() calls, and this causes too many repaints when the
ImageObserver in question is a Component.

        * gnu/java/awt/peer/gtk/GdkGraphics.java:
        (drawImage): Don't notify the image observer for offscreen images.
        * gnu/java/awt/peer/gtk/GtkImagePainter.java:
        (setPixels): Don't notify the image observer if all
        pixels are set at once.
