I've always wondered what a Type 1 hinted font uses to decide
what "real" size it should attempt to optimize for. Does it use
the font's scale factor, the graphics state scale factor, or
the product of these? If it only uses the font's scale factor,
then one can scale the coordinate system and do photographic
reduction to increase resolution. This fails if an application
is using a graphic state scale factor to enforce its own
coordinate system. Is there a device parameter that the font
uses to decide the physical size of a character, such as a dpi
variable?  If one could change this, then photographic
resolution enhancement becomes (computationally, not
necessarily optically) trivial.
