Re: problem with layers and line spacing

["Brian R. Landy" <landy@alumni.caltech.edu>]

Aha.  When I'm not using \startsetup...\stopsetups things are more  
forgiving; once those are in place things became a little more strict  
in two regards --

- The \switchtobodyfont (or, more technically accurate, the  
\setupinterlinespace) must be inside of the \framed.  I had tried it  
both ways and had never seen the difference because of...
- Not terminating the final line with \par.  If my case had required  
three lines I would have seen the issue, because the first two lines  
would have had the proper spacing under one of my tests..

Interestingly if I nest more \frameds, each one needs it's own  
\setupinterlinespace.

One more interesting point, in case this helps anyone out, is I find  
that the behavior also changes if \framed has an offset vs.  
offset=overlay or offset=none.  To get the proper line spacing when  
there is an offset you need to \switchtobodyfont both inside and  
before \framed.  With offset=overlay or offset=none, it is only  
necessary to \switchtobodyfont inside \framed.

I found that using style={\switchtobodyfont} was ignored in this case,  
but Wolfgang's suggestion (in another email) of creating a separate  
\startsetups/\stopsetups block and passing it via setups= to \framed  
worked perfectly.

Hans, Wolfgang -- thanks for your help!
