Comment (by stippi):
I think the poor text rendering also depends a lot on the specific font.
Nobody complains much about the default DejaVu fonts, since those contain
hinting bytecode which works well with the hinting mode that Haiku uses
from Freetype. Other fonts don't contain it and often it results in no
hinting being done at all, especially for !OpenType fonts it seems.
http://www.antigrain.com/research/font_rasterization/index.html contains
code which shows how to use the Freetype auto-hinter to do vertical
hinting only, bypassing the need for any subpixel filtering define. I
think it works nicely, although it looks better with sub-pixel rendering
and filtering than with gray-scale rendering.
