[Fixed] Rotation + scrolling inconsistency

[Gez]

Suppose you have a floor that is scrolling in a direction thanks to Scroll_Floor, but the texture is rotated 90°. This will also rotate the sense of the scrolling for the texture, but not for any object on it!

Preferably, the scrolling would be applied after the rotation, so that the texture scrolls in the direction given; however if it is undesirable for some reason I suppose then carried things should at least scroll in the same direction.
