<pre>I think I figured how to fix it. Let's keep hysteresis disabled from the
beginning, and then every time a finger seems still, apply the simple algo from
point "1" of the prev. comment. Do it 5 times in the row, and if at least one
of them showed wobbling, enable hysteresis, otherwise assume FW filters.
The "5 times" is to workaround possible frame losses. I think it is impossible
to workaround the problem completely (well, not without paying unnecessary CPU
load by peoples with good touchpads), but we can reduce the possibility of the
losses' influence down to a neglectable minimum.
I gonna check if I've got enough time & knowledge to try writing the code these
holidays.</pre>
