-Subject: subclassing devices - fix put_image method
-
-The subclassing devices need to change the 'memory device' parameter to
-be the child device, when its the same as the subclassing device.
-
-Otherwise we end up trying to access the child device's memory pointers
-in the subclassing device, which may not contain valid copies of
-those pointers.
