16b tilt/pan #2 - chaser steps thru - a wobble

[GGGss]

As promised in numerous threads, I'm digging deep into the 16b MSB/LSB issues.

Issue #2: chaser has 2 identical (cloned) scenes - this introduces a wobble in between steps due to LSB values?
Difficult to detect but visually noticeable (!)

Project is attached,

* 1 scene with a mover which has fine tile/pan capabilities. Set fine value different than the course value.
*clone this scene
*add these to a chaser
in the preview, the beam stays dead center
*go produce
*plays with the 2 scenes (inside a solo frame) -> beam still dead center
*press play to chaser -> You instantly see the beam deviate from the set dead-center [see issue #1]

Issue #2: 2 identical scenes in a chaser does weird stuff to the LSB values (with fade times ??)

Now it comes ... at about 0:43 in the video, you'll notice a 'wobble' when the (identical) scenes switch (or fade or whatever)
