MovingPlanes are not correct

[Helco]

Most notably with e5021, MovingPlanes do not rotate correctly with non-default parent orientations causing a number of bugs e.g. in the cloud realm (1030, 1032, 1040)

Additionally the texture animation does not loop seamlessly

7cd37e1 fixed some general parts of MovingPlanes but not all. Good thing that useDirection is only used in e5021, but I need more time (and probably dynamic analysis at this point) to figure out what horrible math is causing Zanzarah to render these two quads.
