I've seen xf86-input-synaptics patches floating around that try to detect
jumps-because-of-averaging from the size of delta and discard but it is easy
to be mistaken.  Probably its better to detect BTN_TOOL_DOUBLETAP
transitions back to 0 and treating similar to both fingers being lifted to
account for expected jump.

Looks good. Detecting "finger configuration changed" based on the number of
fingers is probably the closest one can get to MT behavior without actually
using it.
