I submit that this may presently be the 95% case of present usage of
e.g. an ODF text or presentation document :-)

Line and character placement. The WWW Acid3 test turns this into
"pixel perfect" by making the test download given test fonts as well -
if an ODF is layout-perfect, then with the same font it *should* be
pixel-perfect (unless I've missed something).

Layout-perfect should solve that.

Or "layout-perfect". As I say, if a standard test font (what's free
enough? I suppose a test font can be created ... Latin, CJK, symbols
...) can turn that into "pixel-perfect", then that's very good indeed.
