Haven't we been through this some years ago? What Paul is describing is an artefact of saccadic scanning, the automatic movements by which the eyeball swivels and jitters as it scans the world (and which is usually edited out by the brain's visual constancies). If you stare at something against a plain background, the edges of the object of your scrutiny get displaced, blurring out into an `aura' around it. Big deal.
