Document and fix vanilla bug with smoke rendering

[Archez]

Documents and fixes an incorrect gfx setup call used for the chimney smoke effects. The setup was run on OPA when the actor is actually rendered on XLU. This means the gfx would inherit setup from the previous XLU actor.

In the case of Romani Ranch at night during the Aliens attack start cutscene, the UFO lens flare renders right before the smoke and causes it to appear in bright white when its alpha should be close to 0. Most likely there is floating point precision differences that prevents this from occurring on console (the smoke effect has a check for > 0.0f to even render in the first place).

I've opted to fix the gfx setup to address the smoke effect in the Aliens cutscene.

The Stock Pot Inn had the same bug, so I opted to fixed that too.
