Now I can make both bPrt and bStretch true, if I enable  "Use printer
metrics for document
formatting" and insert some code in  PrintOrPDFExport to set ScaleX and
ScaleY.
I guess I can continue with that for my unit test. Interestingly, I didn't
find any place it is set for the printer.
I wonder if it is something that is no longer useful. In that case, we may
remove the code completely.

Thank you.
