You can, but why should you?   We need to think about this in 
terms of usability requirements and use scenario constraints, not 
in terms of what is possible programatically.

1. There is no need to recompute the layout 60 times per second 
in this use case. Maybe it is better to have 2 types of layout: 
one static and one dynamic.

2. On some displays any type of motion looks really bad because 
the screen refresh is slow (high latency). E.g. electronic ink

You can have scrolling, but it makes for very poor usability.

If you create a UI for controlling big dangerous equipment then 
you don't want the information to be off-screen.
