[NTG-context] pagenumbers in margin

[GEERT at telefonica.net]

Hello,

As I told before, I want the grey box as defined in the page numbering 
(see below) to appear with its outer border aligned to the outer border 
of the outer margin.  Right now, it aligns with its inner border to the 
inner border of the outer margin.  I tried with uitlijnen=buiten but 
without success.

Here is a minimal file, as asked for : 


\def\mijnpaginanummer#1%
	{\startkleur[wit]
	\inlijnd 
kader=uit,achtergrond=kleur,achtergrondkleur=middelgrijs,breedte=2.5cm,h
oogte=1.1cm]%
	{#1}
	\stopkleur}
\stelnummeringin	[variant=dubbelzijdig,plaats={onder,inmarge},%
			commando={\mijnpaginanummer}]
\stellayoutin		[breedte=19cm,
			hoogte=14.9cm,
			kopwit=0cm,
			rugwit=1cm,
			hoofd=2.5cm,
			linkermarge=1.2cm,
			rechtermarge=1.2cm,
			linkermargeafstand=0cm,
			rechtermargeafstand=0cm]
.......
