Camera tracking integration

===========================

Fixed threading issues used to happen when compositor tree
and rendering happened in the same time. Problem was caused
by cached camera intrinsics stored in MovieTracking structure
and access to which wasn't thread-safe.

Now each movie distoriton mode stores it's own camera intrinsics
in it's storage which makes compositor (un)distoriton be totally
thread-safe and this also makes compositor tree faster when
(un)distortion happens on images with different resolution.
