calcMinMaxWidth in AutoTableLayout...

[David Hyatt]

... uses ints to compute a maxwidth, which can sometimes be very large, 
i.e., larger than the maximum short value.  When you assign back to 
table->m_maxWidth, you end up with a negative number for the max width.

This was the cause of the CNN bug I was seeing.  Right before doing the 
assignment I just added this to fix the bug:

     // Max widths can overflow. We need to bounds check them.
     if (maxWidth > 10000)
         maxWidth = 10000;

     table->m_maxWidth = maxWidth;
