Removing space between figure and caption

Removing space between figure and caption

[Brooks Moses]

I'm working on a presentation in ConTeXt, and running into a problem with 
some figures; I can't seem to figure out how to get things to do what I 
want.  Here's a small file that demonstrates the problem:

---------------------------------
\setupoutput[pdftex]
\starttext
\tfd \setupinterlinespace

\setupcaptions[number=no]
\setupcombinations[distance=5mm]
\placefigure
   [here]
   {none}
   {\startcombination[2*1]
     {\scale[width=3in, height=2in]{X}}
     {\bfc Caption 1 \crlf Line 2}
     {\scale[width=3in, height=2in]{X}}
     {\bfc Caption 2 \crlf Line 2}
    \stopcombination}
\stoptext
---------------------------------

My problem is that space between the figures and the captions is much 
larger than I'd like.  In the actual document, the figure contains its own 
whitespace, and so I'd like the top of the caption text to be right up 
against the bottom of the figure.

Also, I'd like to make the spacing between the two caption lines a lot smaller.

How can I accomplish this?

Thanks,
