I would like to shrink the whitespace at the top and the bottom of a  
framedtext.
Like thus:

	not this                         but this
------------------------------      ------------------------------
|                            |      |                            |
|                            |      |   abcd                     |
|   abcd                     |      |   abcd                     |
|   abcd                     |      |                            |
|                            |      ------------------------------
|                            |
------------------------------

I have tried a lot of things with [before, after, top, bottom].
Although [depthcorrection=off] shaves somewhat off the whitespace, it  
is not much nor am I sure if this is on the right track; and it is  
not parametrized.

Someone knows the trick?
