I'm trying to add a draftwatermark to my document, but I'm having some problems with lstlisting.
Whenever I've used lstlisting (for C++ code), the background of the code section is white and overwrites (draws?) the Draft in the background.
I've seen you can change the background colour of the lstlisting, but I haven't been able to find a way to set it to transparent.
What would be the best way of dealing with this?
