Floating point precision

    After banging my head on the wall for some time, I just realized the little twitching annoyance in our timeline was caused by miniscule floating point adjustments to the timeline extends we do at every frame. When the desired timeline position is almost the same as the current one, we make very small (similar to machine epsilon) which can sometimes cause one pixel jumps on the screen.

   Now we know we need to watch these issues more closely.
