[NTG-context] grid and \textrule

[wwl at musensturm.de]

Hallo!

I use 

\setuplayout[grid=yes]

and a chapterdefinition which looks like:

Author
-------------------------------------------------

                                            Title

Text text text ...

The hor. Line above is a \textrule
and the vert. spacing between author and line and line and Title 
resp. should not depent on the grid. So I can not use 
\placeongrid{textrule} in my chapterdefinition. I have to do this
afterwards.

\blank[force,3.9pt]

In short:

\setuplayout[grid=yes]
\def\Sync{...}
\showgrid
\starttext
Bla Blub
\textrule
\Sync
Bla Blub
\stoptext

How should \Sync be defined to snap on the next gridline?

My solution is 

\def\Sync{\blank[force,7.4pt]}% try and error

isn't there a better solution?
