I just got tow colleagues to look at this document with various viewers and they 
both agreed with me that the borders look fine. It is certainly true that 
keepInFrame will brutally truncate stuff if you use that mode. Truncate should 
logically only be used when you are debugging (there may be other use cases, but 
I can't think of them right now). We don't normally want to truncate content.

ReportLab's box model is arguably wrong as we don't really deal with stroke width.
