Change transformPresentingView:percentComplete: in CHBInteractiveModalRevealTransition to get opening door perspective animation working interactively:
- Move transform3D.m34 to straight after assigning transform3D to CATransform3DIdentity as in this example: http://stackoverflow.com/questions/347721/how-do-i-apply-a-perspective-transform-to-a-uiview

Change transformPresentingView: in CHBModalRevealTransitionController so perspective animation looks similar to improved interactive animation:
- Move transform3D.m34 to straight after assigning transform3D to CATransform3DIdentity as in this example: http://stackoverflow.com/questions/347721/how-do-i-apply-a-perspective-transform-to-a-uiview
- Change rotation angle from 1.5 * M_PI to 0.5 * M_PI (i.e. 90deg).
