Accidentally, I've also found `Helvetica Neue LT Com 65 Medium' (2.01
from 2006). My assumption was correct: The `gasp' table of this font
asks for monochrome rendering in the range 9-15ppem.
However, I see strange hinting for certain ppem values. For example,
the monochrome version of `h' at 11ppem misses the left stem, or the
`C' at 10ppem lacks the middle part (see attached image). I *can't*
believe that this is FreeType's fault, given that those strange
rendering results are mainly due to DELTA instructions which shifts
certain points at certain ppem values by a fixed amount. Something's
is going on here, and it would be interesting to know more details.
Do you have a chance to check monochrome rendering of this particular
font on Windows?
