I build a small switch, that can "disable" theese 6 code-lines.

char* scale = getenv("noscale");
if (!scale || (scale[0] != '1')) {
    x *= vp.Width / 2;
    y *= vp.Height / 2;
    z *= vp.MaxZ - vp.MinZ;

x += vp.Width / 2 + vp.X;
    y += vp.Height / 2 + vp.Y;
    z += vp.MinZ;
}

If you use that, you can play "Tomb Raider 4" without disturbing other games:
export noscale=1
wine tomp4.exe

I know that this is a quick&dirty workaround, but it works :)
