Hi all,

Because no one replies to the latest Pete French's letter until now,
let me say something.

I also have the same trouble as he got into.  Until I read his email,
I believed that that's a kind of machine dependency problem.  (I refrained
from talking about it because I had been busy to make GNUstep understand
my mother tongue.)

I strongly believe this should be fixed as soon as possible (at least
before the version number becomes 1.0.0).

So I raise the same question again here in order for everybody in this
list to note the isssue again and discuss what to do.

Thank you.
Kazunobu Kuriyama

Then you would have many small gaps, so it wouldn't be as noticeable. It
would probably hurt performance, but I haven't done much benchmarking of
it.

It might be interesting to try - arre the cumulative errors cause by
errors in the hints or rounding errors as it moves along the line ? If its
the latter then maybe it could be fixed by moving to using doubles instead
of floats ?

I also notice that PSshow() does the correct thing - this is what I was using
until this week, but as I want OSX portability I am moving away from it, which
is proving a little fraught!

I'd be interested to hear what other people do to get around this - I cant
be the first person to actually try drawing text on the screen after all :-)

-bat.

PS: preseuably this is also the cause of other oddities - like missing the last
character of messages in alert panels, or the missing of the last character of
a name in an NSBrowser ? I see those quite regularly too.
