not really, all valuators sent to the clients are always absolute (with the
exception of the ones in RawEvents). so even though the driver posts events
as relative, they're just added to the current value and sent as absolute
anyway.

this makes the whole issue rather tricky, because i'm pretty sure that most
users would scroll down more than up, so you _will_ get overflow at some
point. not sure what to do here...
