fix-last_issued-ts_filter_median.patch
- Decimation_below was not being used in the median filter. Fixed.
- Decimation_below should be small. There's no need to change many
points in the median filter if we're moving slow. In this way we
will filter more noise.
- Now we deliver 2X input events -- 1 each 5 milliseconds.
(side effect of the previous two changes)
- We should omit the last point before the UP event but I think this
belongs to user-space. I'm programming a tslib filter ("skip") and
if it doesn't work will I'll send a patch later to skip the last
point in the driver.
