Re: New GTK+ anti-aliasing patch posted

[Michael L Torrie <torriem cs byu edu>]

Antialiasing is cool, but I don't always want it on all the time.   I
could of course set up certain directories of fonts to be antialiased, and
have others not be.  On the one machine I tried, it didn't do anything
(It's XFree 4.0.2 using nvidia's glx drivers 0.96) so that probably means
my render extension isn't available.

Being able to turn it on or off somehow (globaly) would be something
desirable.  I would expect it in the Gnome API, but I guess you'd need
something in GTK also.

Another thing that may be advantageous is to only anti-alias fonts above a
specific point size.  I find anything below 12 pts and above 9 pts to be
very blurry and hard to read when anti-aliased.  It would be nice to
specify a threshold (low and high) at which anti-aliasing would work.
(even hard coded for now.)
