Text background that spans the width of the page

Text background that spans the width of the page

[Darksair]

Hi all,

I would like to have a colored horizontal stripe as background for one
line of text.  Sort of like what textbackground does, but I want it to
span the whole \paperwidth, instead of just \textwidth.  At the end of
the day, I would use it to style for example my section heads, or to
highlight one specific \item.  What’s the best way to do it?

you can use textbackgrounds and plug in some mp code that extends into 
the margins ... it depends a bit on what 'line' means here

     \startuniqueMPgraphic{whatever}
         fill OverlayBox
             leftenlarged BackSpace
             rightenlarged CutSpace
             withcolor OverlayColor ;
         setbounds currentpicture to OverlayBox
             enlarged max(BackSpace,CutSpace) ;
     \stopuniqueMPgraphic

     \defineoverlay[whatever][\uniqueMPgraphic{whatever}]

     \framed
       [background=whatever,
        backgroundcolor=green,
        frame=off,
        width=\textwidth]
       {test}%

Thank you for this interesting solution!  I didn’t know one could do
that with Metapost.  This does exactly what I want.
