Issues in OpenGL 16bpp formats support

Hello,

Two years ago I locally fixed some bug with Civilization III game, 
caused by problems with 16bpp format support in OpenGL on joint of Wine 
and Mesa libraries. I described my findings here

https://bugs.winehq.org/show_bug.cgi?id=41930#c60

Now realized that may be bugtracker alone is not enough, and may be 
writing to this e-mail list is better.

I'm wondering if anybody interesting in fixing this issue? I will be 
glad to work with somebody to fix this problem in the main Wine brunch 
(just don't know correct workflow for upstreaming and discussing fixes 
like that).

With best regards,
Vyacheslav Chigrin
