Rise and fall times of Chronogram

[Lars Clausen <lars raeder dk>]

Could some with experience of electrical engineering take a look at
http://bugzilla.gnome.org/show_bug.cgi?id=355069 and see if the proposed
change fits with normal usage?  References would be nice.  I just don't
want to change this and have everybody else go "you broke it!" at me.

Thanks,
-Lars
