This was the original behavior introduced in

wheel emulation, for some reasons beyond time, got the value from
pEvdev->vals, then set the value back into pEvdev->vals. Alas, that value is
always 0, hence oldValue is zero and the delta is nil.
If we're not in relative (touchpad) mode, store the current value in
old_vals, so they're retrievable for the next event.

The server switched to pc105 with version 1.8 (1df4bd601).
The evdev model resolves to pc104 anyway, so this commit has no real effect
other than to switch from a catch-all rule to explicit.
Use pc104 so this is easy to find for those investigating the code and
wondering why. pc104 is the 'correct' geometry for the us layout, which is

Evdev is a 100% stateful protocol. The following represents three
touches. Two touches begin and end at the same time at (500, 500) and
(1000, 1000). The third touch begins after the first two end, and is at
(500, 500).
ABS_MT_SLOT 0 /* Set touch slot */
ABS_MT_TRACKING_ID 0 /* New touch with ID 0 in slot 0 */
ABS_MT_POSITION_X 500 /* Initial X position */
ABS_MT_POSITION_Y 500 /* Initial Y position */
ABS_MT_SLOT 1 /* Set touch slot */
ABS_MT_TRACKING_ID 1 /* New touch with ID 1 in slot 1 */
ABS_MT_POSITION_X 1000 /* Initial X position */
ABS_MT_POSITION_Y 1000 /* Initial Y position */
SYNC /* End of frame */
ABS_MT_SLOT 0 /* Go back to slot 0 */
ABS_MT_TRACKING_ID -1 /* Touch in slot 0 ended */
ABS_MT_SLOT 1 /* Go to slot 1 */
ABS_MT_TRACKING_ID -1 /* Touch in slot 1 ended */
SYNC /* End of frame */
ABS_MT_SLOT 0 /* Go back to slot 0 */
ABS_MT_TRACKING_ID 2 /* New touch in slot 0 with ID 2 */
SYNC /* End of frame */
ABS_MT_TRACKING_ID -1 /* Touch in last slot (0) ended */
SYNC /* End of frame */
Note that touch 2 has the same X and Y position as touch 0. This is
implied because no new value was emitted for slot 0. In fact, Linux will
not emit an event in the same slot with the same event type and code
unless the value has changed. Thus, we can only assume that all the MT
valuators have the same values as they were when they were last sent for
the given slot.
This change adds an array of valuator mask to hold all the last valuator
values that came from evdev for each slot. When a new touch begins, all
the last values are copied into it.
This patch assumes initial axis values of 0 in each slot. Linux and
mtdev do not provide a facility to query the current values of axes in
each slot yet. This may cause spurious incorrect touch valuator values
at the beginning of an X session, but there's nothing we can do about it
right now.

For touchpads, rel_queued may be on (due to abs to rel conversion) but the

when the data is posted to the server.

Touchpads send garbage data between BTN_TOOL_FINGER and BTN_TOUCH. This
leads to cursor movement towards invalid positions (bottom left corner,
usually).
Add a new flag "use_proximity" as a delimiter for BTN_TOUCH handling. If
unset, the actual proximity bits are ignored, no proximity events are sent
and BTN_TOUCH is used for the tool handling.

The Xen Virtual Pointer device exports both absolute and relative axes from
the kernel device. Which coordinates are used is a run-time decision and
depends on the host-specific configuration.
0a3657d2ee broke these devices, and they are
now unusable out-of-the-box as there is no configuration to cover them.
This patch converts the IgnoreAbsoluteAxes and the IgnoreRelativeAxes
configuration options into a trinary state.
1. If unset, configure the device as normal by trying to guess the right
axis setup.
2. If set to true, ignore the specific axis type completely (except for
wheel events).
3. If set to false, explicitly 'unignore' the axis type, alwas configuring
it if it is present on the device. This setting introduces seemingly
buggy behaviour (see Bug 21832)
1. and 2. replicate the current driver behaviour.
The result of 3. is that is that if a device has absolute axes and the
options set to false, both axes will be initialized (absolute last to get
clipping right). This requires axis labelling priorty to switch from
relative first to absolute first.
Relative events are forwarded into the server through the absolute axes,
the server scales this into the device absolute range and everyone is happy.

Regression:
If a user has multiple buttons mapped to the same button number, the
number of buttons counted is set to a wrong value. e.g. a button
mapping of 1 1 1 for a mouse with three buttons would only initialize 1
button to the X server.
In the future, the user cannot change this button mapping as the server

The user-supplied button map (option ButtonMapping) shouldn't matter when
counting the buttons. Only the driver-internal mapping (BTN_0 -> button 1,

Wheel emulation works for both horizontal and vertical axes. Thus, if a
device doesn't move in perfect straight line, scroll events build up on the
respective other axis.
In some clients, scroll wheel events have specific meanings other than
scrolling (e.g. mplayer). In these clients, erroneous scrolling events come
at a high cost.
Thus, if a scroll wheel event is generated for one axis, reset the inertia
of the other axis to 0, avoiding the buildup of these erroneous scrolling
events.
