Well, we should (and I have a patch to this effect sitting in my tree for a
long time now). But the best would be, of course, to support both 24/24 and
24/32 properly.

But for that I need a 24/24 system to test on :-)

Well, I was just saying this as you told that you needed to export this
function and so I tried to propose a solution. I do not have a strong
opinion on this anyway :-)

Well, it's just that if I want to play in 640x480 with my standard 800x600
desktop I could change the resolution in HalfLife for example without having
to change the Wine config :-)

But I agree that it's not that big a problem.

Yeah, this could be possible.

Anyway, there is not only Desktop mode but people which either do not have
XVidMode or who have it disabled... Should they always play HalfLife or
games using their desktop size or will they be allowed to change the
resolution ?

For exemple, I will always disable XVidMode in my config (I hate automatic
switch as when I want really to play, I start a second X server at the right
size :-) ). But I sill would like to be able to change the size of the games
I want to debug.

Well, this is what Wine did for 10 years now and nobody ever complained :-)
