Moves and drags are working for screens that send multitouch events but not for screens that send simple touch events. The following does not generate a move or drag event:

EV_KEY BTN_TOUCH 1
EV_ABS ABS_X 0
EV_ABS ABS_Y 0
EV_SYN
EV_ABS ABS_X 1000
EV_ABS ABS_Y 1000
EV_SYN
EV_KEY BTN_TOUCH 0
EV_ABS ABS_X 1000
EV_ABS ABS_Y 1000
EV_SYN

Added some tests to FuzzyTapTest to check for this: the tests are tap3(), tap3a() and tap3b(). All fail.
