Hi,
The updateBufferedImage() method calls in BufferedImageGraphics didn't
take into account the possibility that pixels might have been shifted
(ie, the shiftDrawCalls field in CairoGraphics2D).
This little patch extends the update region in these cases.
Cheers,
Francis

* gnu/java/awt/peer/gtk/BufferedImageGraphics.java (draw): Extend
updated
region to account for pixel-shifting.
* gnu/java/awt/peer/gtk/CairoGraphics2D.java (shiftDrawCalls): Made
proctected.
