We set it this way because blur can be very time consuming (30 seconds and
more, depending on the image size and the zoom level).
Many users were annoyed that moving the slider or the preview image immediately
resulted in the preview calculation.
So we removed the automatic calculation so that the user can select the preview
window and the filter settings and hit "try" to finally see the results.
Since the preview is only calculated for the preview window, moving the frame
"deletes" the target view, since this data is simply not present.
