That is not sufficient as the application may want to put much more
complex rules on how the pointer moves (such as limiting it to a rectangle).
As a practical matter the applications that want a slow scrollbar want
*exactly* the same acceleration as before, just that the resulting
position is scaled down. Forcing them to replicate the code that the
compositor is doing seem mistaken.
The only thing that will work is that the application can directly set
the cursor location while it has the grab.
