Description Brian Ewins 2006-12-16 05:00:43 UTC 
Continuing bug 9350 (rather than post multiple patches on a single bug)

cairo-scaled-font.c rounds glyph positions to the nearest pixel, but this code
path isn't used by the atsui backend, resulting in small differences in the
output from the ft backend.

adds rounding with the same todo comment as in cairo-scaled-font. applied after
