It's definitely needed.

Does this have anything to do with printing?  As I recall, printing
also requires a display?  Does that make printing somehow tied to
screen (or framebuffer) resolution?  It would be best if could
generate vector graphics of some kind (PS, pdf, svg, whatever) that
don't have a fixed resolution.
