Well, the resolution should be increased and the doc reconverted when
the up-scaled image becomes blurry.  But how should emacs know when you
think it becomes blurry?

I guess this could be done somehow.  But do you want to center to make
the contents a bit larger and not to see the margins?  If so, then
slicing to the bounding box (`s b') followed by fitting to width (`W')
may be the better approach.
