For the most part this is all it seems to do. Differnt mertics and
Windows styles. You can see examples of this by looking at the sources
for the edit control. With the common diaglogs there is code that
implements a Win31 theme if a you want to use it with a Win32 app. I
was just going to submit a patch to rm -fr this code but if people want
to use a 3.1 style on a new app I guess we should figure a way to do
this in the theme support.

I dont know what the best method is going to be to handle the old
Winelook option. I think it should just go to /dev/null but I dont know
what the result will be on older Win16 apps running with a 9x Winelook.
Can anyone comment on this? Is there still a large number of people
that want to keep this around?

Thanks
Steven
