o be a good vid-detective, one should look at
vidface/facets and vid-face/style.
BMX (by my experiments)
'facets is the part 'layout used to construct the face,
and 'style the style its based on.
thats a LOT fewer source :)

Cool :)
but 'info allows copying of text, so maybe the feel-way is usefull?
to block a face used once following:
i placed a face in front of the original face,
this gets now all mouse-events.
the face was a filter, so the original face was darkend.
a filter with
color: font: para: text: data: image: none
effect: [blur colorize 0.0.200]
but i remember this with change in the future,
http://www.escribe.com/internet/rebol/m15951.html
then effect will be
effect: [mergecolorize 200.0.0]
now, could not resist trying it :)
rebol [todo: {mark is-disabled somehow, seperate handling of field/info}]
