Title:
Devices which do not use MT_SLOTS protocol can create invalid touch
states
Status in Mir:

Bug description:
"Certain devices" do not use the MT_SLOTS protocol for their
touchscreen. In such cases (and perhaps in particular...when they omit
certain 'redundant' tracking ID's) invalid touch states may be
produced.
On "such a device" you could run mir_demo_standalone_input_filter and
tap once...
observe strange movement to 0,0...further investigation, i.e.
ANDROID_LOG_TAGS=*:v MIR_SERVER_LEGACY_INPUT_REPORT=log would reveal
pointerCount becomes frozen at 1.
The strange movement to 0,0 is caused, when detecting that the
pointerCount hasn't changed but an input frame is being processesed,
the stack infers it must be processing a motion event but of course
there are no coordinates in the current pointer data.
