Hutterer: Synaptics pointer acceleration
For this week's development horror story, it would be hard to do better
than Peter
Hutterer's quest to figure out how pointer acceleration works in the
Synaptics driver. "Also a disclaimer: the last time some serious
work was done on acceleration was in 2008/2009. A lot of things have
changed since and since the server is effectively un-testable, we ended up
with the mess below that seems to make little sense. It probably made sense
8 years ago and given that most or all of the patches have my signed-off-by
it must've made sense to me back then. But now we live in the glorious
future and holy cow it's awful and confusing."
