	* gnu/java/awt/peer/gtk/BufferedImageGraphics.java
	(drawGlyphVector): Clip updated area to glyph bounds.
	* gnu/java/awt/peer/gtk/CairoGraphics2D.java
	(createPath): Eliminate distortion when pixel-shifting rectangles; separate
	x-coordinate and y-coordinate pixel shifting.
	(shifted): Removed method.
	(shiftX): New method, recognising scaling transforms.
	(shiftY): New method, recognising scaling transforms.
	(walkPath): Separate x-coordinate and y-coordinate pixel shifting.
