Bug #: 31393
           Summary: Nvidia force antialiasing no longer works

After AlwaysOffscreen has become enabled by default, games such as GTAIII and
GTAVC (which are unaware of FSAA) can't benefit from nvidia antialiasing
settings out of the box. I'm not sure if it's intended result, but despite it
being possible to disable it back, new default seems no good to me as e.g. on
Windows it's enough to set antialiasing in the driver utility and there's no
need to change D3D configuration.
Maybe wine should check whether default render target is multisampled and
toggle the default?
