prepare_image_for_display sets data.ptr_val in the image structure as
well.
What happens when the image is manipulated after it's been first drawn?
I assumed that data.ptr_val would be invalidated at that point, as is
done in x_clear_image_1.
Are you concerned about postprocess_image?
One would have to invalidate the pointer and free the image when
anything is done to the image there (x_build_heuristic_mask is called,
or QCconversion is given).
Any other places where image manipulation can take place?
