The frame parameter code and the x_set_frame_alpha function
were written by Ryo Yoshitake.  He is ready to sign.

The lower_limit variable and the x_set_alpha function originally come  
from
mw32fns.c (e.g. mw32_set_frame_alpha in l.1019-1078) in Meadow,
although they look differently because of my extensive modification.

connection)
I am contacting Mr. Horiguchi, the author of the relevant part.
I already signed the paper.

The first version of the patch was developed by Takashi Hiromatsu.
I am waiting for his response in order to make sure.
Practically, his code in ver.1 was completely
replaced by Yoshitake-san's code (ver.2) and
my code based on Meadow (ver.3, ver.4).

Yoichi Nakayama wrote twenty lines to improve performance,
surrounded by the following brackets.
He agreed to contribute, but he modestly described that his  
improvement is "minor".

   /* return unless necessary */
   {
      ...
   }

I'll write to this list if I have an update.
