Hi,
We're using ff-memless in Sailfish OS for vibrator / haptics support,
and I've noticed this annoying issue with the periodic force feedback effects
that declining attack ramps don't work with it properly.
I.e This kind of effect:
\
\
'-------------.
\
\
turns into something like this:
--+
|
+-------------.
\
\
It turned out to be quite simple fix to get declining attack ramps
and rising fades to behave linearly. Please check, comment, and apply
if seen fit.
