Alright, I spent last night making this hack presentable. Here’s my
attempt to make SDL Do The Right Thing when doing fullscreen in a
Xinerama environment.
It, well, works for me. Tested only with Dose 2 And testgl so far as
thats all I have handy at the moment. Lost my UT cd. Damn it…

Dose 2 still leaves a managed window at +0+0, but near as I can tell its
not SDL thats doing it. 
Still some improvements to be made, like say an environment var to pick
what head to display on if assuming 0 is wrong.
And my autoconf patch is BS. Someone who’s an autoconf wizard please
write a real entry. Heh.
Remember to run ‘autoconf’ to rebuild configure after patching.

Test it please.
