....Dinu all numbers in PDF are represented in points using a 16.16
fixed point signed binary representation. So internally numbers are
limited to the range +/- 32767.999984741211. The smallest non-zeros are 
+/- 1.52587890625e-005 (ie +/- 1/(2**16)) all this means that your
largest canvas is around 11.55982221683926 meters on a side.
