[Desktop_printing] Just how much of OpenPrinting Vector is in ESP ghostscript?

[Fujinaka, Todd]

It's going to take me a while longer to figure out the structure of the
code (if I figure out the structure of the code) and it appears that
OpenPrinting Vector could still be a moving target. I figure I'd better
just ask, how much of OpenPrinting Vector is in ESP ghostscript? And if
was a printer manufacturer, how much more would I need to create an
OpenPrinting Vector filter for my printer?

Thanks,
Todd
