CVS commit by aacid: 

Implement isAllowed for the pdf generator, Enrico is implementing the use of it in \
pageview etc. IMHO this is not a feaute but a bug-fix as if this is not implemented \
we let the user copy text and print from PDF that are protected against and wether we \
may like it or not is what the spec says and we could get in problems if someone \
copies text from a protected PDF using our tool.
