Transition Move In L does not like opposing screen orientations

[totallyevil]

Scene1 : portrait
Scene2 : landscape

From Scene1, CCTransitionMoveInL to Scene2. The scenes are jumbled and experience a hiccup during the rendering at the half-way point of the cross rendering, and then they jump to replace scene1 with scene2.

The end result works, but the transition does not work.

Does the same for MoveInR as well.
