+	* Source/cairo/CairoGState.m: 
+	Add a call to cairo_pattern_set_extend(pattern, CAIRO_EXTEND_PAD);
+	on the pattern used to draw images. This keeps the edges of images
+	crisp when the are scaled up.
+	The description from the Cairo docs is: "pixels outside of the
+	pattern copy the closest pixel from the source".
