Re: vertical text in table cell with height None

I think you might not be specifying a height for the row in question. By default 
the width of a paragraph is the same as aW (in this case aH). We improved 
paragraph wrapping in later reportlab so this is just exposing a bug in how 
layouts used to fail ie the old case didn't wrap properly and then wrote outside 
the actual height of the cell. Since paragraphs don't ask for extra width the 
dynamic row height mechanism isn't going to help.
