Hi Linoel,
If you use unRefImageDataAfterApply then the image is discarded as
soon as the image data to download to OpenGL, which helps reduce
memory consumption significantly so is great for real-time sims.
However, if you discard the image data then you can't later use to it
write out to disk. If you want to write out data you can't use this
feature.
