Autolayout Support

[Littlequark]

Rotation and pinch work fine but dragging оf white "crop frame" always crashes with the same result in this method:
[PECropRectView resizeControlViewDidResize:].

** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [177 nan]'

libc++abi.dylib: terminating with uncaught exception of type NSException

and same thing when not using any AutoLayout at all.
