Works totally similar to camera motion blur and majority of the changes are related on just passing extra arguments to sync() functions. Couple of things still to look into: - Motion pass will not include motion caused by the zoom. - Only perspective cameras are supported currently. - Motion is being interpolated on projected coordinates, which might give different results from constructing projection matrix from interpolated field of view. This could be good enough for us, but we need to consider improving this at some point. Reviewers: juicyfruit, dingto Reviewed By: dingto Differential Revision: https://developer.blender.org/D1383
