Add test for vertex shader `oPts` behavior #74

Open abaire opened 2 years ago

I'm guessing oPts will behave like oFog in that only the x component is really used and it gets set by the most significant component in the case of a swizzle. E.g., oFog.yw = r1.yw actually sets oFog.x = r1.y and the rest is either ignored or may be practically irrelevant.
