It seems to completely ignore postprocessing for PNG images. Didn't
you say that "One could remove the reference to the original image as
soon as any kind of processing is done in order to maintain
compatibility."?
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?
