Hit F4.  The current zoom level will be set to match the nearest OSM zoom 
level.  The fuzziness of OSM tiles will go away, because they'll be used
at their intended scale instead of being scaled up or down to match the current
xastir zoom level.

This is somewhat hidden, but is set in the ".geo" file for each OSM tile
set.  For example, in OSM_tiled_mapnik.geo, we have:

# When defined:
# OSM_OPTIMIZE_KEY will change the map scaling to the nearest OSM zoom level.
# OSM_REPORT_SCALE_KEY will report the present, scale_x, scale_y,
#   and OSM zoom level, but only for debug level 512 (-v 512)
#
# The values are X KeySym values.
# 65473 = F4
# 65474 = F5
OSM_OPTIMIZE_KEY 65473
OSM_REPORT_SCALE_KEY 65474
