Personally, if changes like this were to be made, I'd rather see them form a
more general client-side caching mechanism, so that it could be used for
more than just pointer manipulation, which, at the end of the day, isn't
actually all that costly since most of the perceived pointer jitter comes
from latency, not bandwidth problems.
