[NTG-context] two features in ViewerPreferences for printing

[Pablo Rodriguez]

Hans,

for a small book I’m publishing online
(https://archive.org/download/ensayo-escritura/ensayo-escritura.pdf), it
would be extremely useful to have two features from the PDF spec
implemented.

These are PrintScaling and Duplex (page 364 of the PDF spec). They are
two entries in the ViewerPreferences.

Both features are extremely useful to avoid issues when explaining
double-sided printing and not reducing margins (in some cases, this
reduction to margins is critical [such as in the sample above]).	

I think this is not only useful to many users. Could these features be
implemented in ConTeXt?

Many thanks for your help,


Pablo
