Perhaps I am confused, but Brian seems to be saying that PostScipt uses
a size-independent outline description for a character in a particular
font, and can arbitrarily rotate it before conversion to a bitmap.

I was under the impression that there was no such size-independent
representation.  Isn't that what the whole hoopla over bit-tuning is
all about?  Certainly MetaFont is incapable of producing a uniformly
great font at 300 dpi resolution, 10 point.  We have used both a Xerox
2700 and an Imagen 8/300, both 300 dpi, but the character of one-pixel
line drawing on the two engines is so different that CMR fonts that
look great on the Imagen were awful on the 2700.

Or is the outline description some incredibly sophisticated
representation that takes all into account?
