Address ghost spots that show up after touchscreen is re-enabled 

When touches are cancelled as a result of a touchscreen being disabled,
the pointers that were down when the touchscreen was disabled show up as
touch spots briefly while a new pointer goes down after the touchscreen
is enabled. Remove these ghost touches.
