Disallow antialiasing for software skinned 2d polys 

Antialiasing is not supported for batched polys. Currently due to the fallback mechanism, skinned antialiased polys will be rendered without applying animation.

This PR simply treats such polys as if antialiasing had not been selected. The class reference is updated to reflect this.
