Actually, I've one more question on this. I need to find out the width 
and height of string as it will be rendered by "showLayout". In the 
basic cairo font api, I write:

-- | Return the bounding rectangle for a text string rendered
--   in the current context.
textSize :: String -> CRender RectSize
textSize s = c $ do
     te <- C.textExtents s
     fe <- C.fontExtents
     return (C.textExtentsWidth te, C.fontExtentsHeight fe)

What are the equivalent functions in the pango world?

Thanks,

Tim
