That explains it.  Test operations in PDF must be enclosed
between 'BT' and 'ET' operators, and text objects are a convenience 
to save users or the canvas from a lot of 'mode switching'
on every drawing operation; they are NOT supposed to be
kept hanging around, used in parallel or re-uses.  We should add an 
assertion to catch misuse of the text object.
