Add test for reading back `oFog.yzw` #75

Open abaire opened 2 years ago

abaire commented 2 years ago

oFog sets the x component with the most significant component in the case of any swizzle. E.g., oFog.yw = r1.yw essentially sets oFog.x = r1.y.

Add a test to see what the other components get set to in various cases where x is not mutated. The FogVec4CoordTests already confirm the behavior wrt. setting x but do not do anything with yzw.
