Related: tdf#155092 translate Y coordinate for height differences
When in live resize, the NSView's height may have changed before
the CGLayer has been resized. This causes the CGLayer's content
to be drawn just above or below the top left corner of the view
so translate the Y coordinate by any difference between the
NSView's height and the CGLayer's height.
