Filtering is not actually merged in the same TS driver. We could
replace it with some basic averaging with little effort. We improved
interrupt handling and avoided jittering with pen-down/pen-up events.
I know it works but I'm sure some cleanup might be needed (perhaps
beyond my knowledge) to make it suitable for upstream.

If it helps I can send a simplified version of the driver that does
not depend on filtering.
Since we don't know Ben's version of the driver then I guess it's Ben's call.

Regards.
