The kernel/udev set the pressure resolution to nonzero to indicate the value
is in a known scale (units/g). We use that information to disable the
pressure axis on such devices - real pressure cannot be translated to
contact size.

This touchpad is a true pressurepad and the pressure axis gives us physical
pressure down. Using it as contact size gives flaky touch detection, so let's
just disable the axis until we do something with that value.

Data in
https://gitlab.freedesktop.org/libinput/libinput/-/issues/225#note_379034
suggests that AES devices have lower noise than the older EMR
devices, so let's try disabling it for those devices.
We can't directly get the AES devices in libinput unless we want to add a
whole bunch of quirks for the various vid/pid combinations. But we can get
that info from libwacom, primarily because we know that libwacom will list all
known AES pens for any device. So we can check for one that we know of (0x11)
and if it's in the list, the tablet is an AES tablet.
Setting the history size to 1 means we never do any actual smoothing.

The current tool type test merely sends BTN_TOOL_RUBBER (and others) manually
and expects libinput to do the right thing. This only tests the perfect
sequence but not test weird devices that behave differently on a tool type
switch.
So let's fix this by setting the tool type as property on the libinput test
device itself, and then emulate the tool switch through litest.
For special devices this will need extra callbacks, this is just the initial
framework to handle those buttons.

This used to do nothing, now at least it does the same thing as the

Putting an EVIOCGRAB on the device before sending those events means no-one
else sees those events - particularly upower. This means no-one else knows the

those are inhibited anyway).

If we know that the tablet mode switch is bogus anyway, filter the event and
don't pass it to the caller. They won't know whether it's bogus so the only
result we get here is buggy behaviour.
This is the simplest solution here, it filters the mode switch at the lowest
level and thus the caller won't know that the tablet even has a mode switch at
all. Where the device doesn't have any other switches it'll also lose the
switch capability.
This may cause issues in some niche cases where the event node only has
that one bit and we now disabled it leaving us with a zero-event bit device.
Shouldn't matter to callers, but let's see.

Where a touch is labelled as palm on TOUCH_BEGIN (edge palms) we would still
feed the touch through the tap state machine. This would trigger the PALM
transition for each state, usually reducing the touch count.
When the touches were later released, the touch count was out of sync,
resulting in an error message. In the case of #488, the trigger was
a single evdev frame with three fingers down, the third of which was an edge
palm:
- touch 1 transitions from IDLE to TOUCH
- touch 2 transitions from TOUCH to TOUCH_2
- touch 3 (the palm) transitioned from TOUCH_2 back to TOUCH
That third transition is invalid, the palm hasn't been seen by the tap state
machine so it should just be ignored.
Fix this by moving making the tap state processing conditional on a touch
state other than TOUCH_BEGIN.

With the previous patches a tablet would ignore a valid proximity out sequence

This quirk was introduced for #248 was caused by buggy input-wacom drivers,

This appears to be the only tablet where this fix was needed, but we've been
playing whack-a-mole ever since to work around the various other tablets that
break with this behavior in place.
So let's revert that fix and hope there aren't any other tablets out there
(and if they are, we can probably quirk those). The revert makes the ISDV4 pen
quirk obsolete (see 9cb089f2b6), so this was
folded into this commit.

This has never been supported through the stack. No device ever had the
required MOUSE_WHEEL_TILT_VERTICAL/HORIZONTAL udev property set, so
libinput never set the right axis source. Neither weston nor mutter
added the code for it. Even if we added wheel tilt for devices now, it
would break those devices. And the benefit we get from having those
separate is miniscule at best.
So let's do the long-term thing and just deprecate this axis source.
The wheel tilt mouse test device remains in the test suite, with the
udev properties set just to verify that we do indeed ignore those now.

Take a snapshot of the time every 10 libinput_dispatch() calls. During event
processing, check if the event timestamp is more than 10ms in the past and
warn if it is. This should provide a warning to users when the compositor is
too slow to processes events but events aren't coming in fast enough to
trigger SYN_DROPPED.
Because we check the device event time against the dispatch time we may get
warnings for multiple devices on delayed processing. This is intended, it's
good to know which devices were affected.
In the test suite we need to ignore the warning though, since we compose the
events in very specific ways it's common to exceed that threshold
(particularly when calling litest_touch_move_to).
