Currently all force effectors can only act on cloth when the force is perpendicular to the surface. This makes sense for wind, but not for other forces; and the user may want even wind to have some friction. This changes effector code to output two force vectors - although you of course can pass the same pointer for both. The force is split between the two outputs based on a new per-effector setting.
