[compiz] Compiz-manager script (Was: --skip-gl-yield)

I threw together a very rough draft of a script:

(See my compiz-script git repo:

It's not too pretty, and only really adjusted for nVidia, so it's
pretty useless at this point. I've only ever actually used nVidia with
direct rendering, so I'll need some input from people with other
setups than mine.

No, you're right. Though there are some checks that would be simpler
in C, I don't think it's really reasonable to write it in C (or any
other compiled languaged) for just those checks.

Yeah... I used this, but slightly diffrent. Basicly -r env, -r args or
-r both. See if it looks sane to you. (Of course what it actually
gives you is, again, pretty useless.)

The script I wrote stores the result of it's test, so you won't have
to do the same tests every time (though they are quick). This also
allows you to easily override the script. It is in no way perfect, but
see if you like the concept, so we'll see if it's worth working
further on it :)

Oh, I guess this actually does what you suggested too, Mike, except it
does it in a single file, but that's not really significant :)
