Hmm. On my 12" iBook with its default screen settings, the original,
non-gamma-corrected image looks much better than the others.
The gamma corrected version has too thick vertical and horizontal
stems and the diagonals all disappear (and the reverse is true on the
white-on-black). The original fonts have some un-even-ness problems too,
but I think that might be because of the hinting. Do you have an image
with the unhinted fonts to compare with? Both non-gamma corrected and
gamma corrected?

IMO, all compositing and rendering should be done in (which?) linear space,
and only be corrected for output media in a final conversion. Preferably by
setting a transfer function in the X server.
