inpututils.c:243:26: warning: comparison of constant 256 with expression of
type 'KeyCode' (aka 'unsigned char') is always false
[-Wtautological-constant-out-of-range-compare]
if (modkeymap[i] >= MAP_LENGTH)
~~~~~~~~~~~~ ^ ~~~~~~~~~~
MAP_LENGTH depends on MAX_BUTTONS which is somewhat arbitrarily chosen. We
don't expect this to ever change, but just in case leave the condition there
so the code is correct if we drop the number down.

tranformAbsolute has a pretty simple job, that of running the X/Y
values from a device through the transformation matrix. The tricky bit
comes when the current device state doesn't include one of the
values. In that case, the last delivered value is back-converted to
device space and used instead.
The logic was twisted though, confusing GCC's uninitialized value
detection logic and emitting warnings.
This has been fixed by changing the code to:
1) Detect whether the ValuatorMask includes X/Y values
2) If either are missing, back-convert the current values into ox/oy
3) When X/Y are present, set ox/oy to the current value
4) Transform
5) Store X/Y values if changed or if they were set before.

A careful read shows that it was always NULL. It hasn't always been; as
the DDX spec indicates, it was the "occluded region that has backing

Introduced in 45fb3a934dc0db51584aba37c2f9d73deff9191d. When a device is
enabled, the master's locked state is pushed to the slave. If the device is
floating, no master exists and we triggered a NULL-pointer dereference
in XkbPushLockedStateToSlaves.

XKB allows to override the BellProc() ringing the 'keyboard bell':
instead an event is sent to an X client which can perform an
appropriate action.
In most cases this effectively prevents the core protocol bell
from ringing: if no BellProc() is set for the device, no attempt
is made to ring a bell.
This patch ensures that an XKB bell event is sent also when
the core protocol bell is rung end thus an appropriate action
can be taken by a client.

This reverts commit d90b5f83010248be65b2039b0b2d0b9e6a4e93cf.
Reverting for two reasons:
* the scaling does not work on devices that don't advertise resolution, and
the default resolution used (100 units/mm) is higher than most devices,
resulting in a significant slowdown of the touchpads.
* the scaling is still affected by resolution changing. The patch worked
before acceleration but since it maps into resolution-dependent dx/dy
coordinates the acceleration may distort the movement after the fact. So the
same input data generates different movements depending on the resolution.
This can't easily be fixed for all affected devices as synaptics has its own
velocity calculation method whereas wacom doesn't. So anything in the server
won't work for both at the same time.
Revert this for now, until a more integrated solution can be implemented.

The goal of all this is to get an x/y motion reflecting the motion
on the device, i.e. a circle on the device is a circle on the screen.
This is currently done by scaling the y coordinate depending on the screen
ratio vs device ratio. Depending on that ratio the movement on the y axis may
be accelerated (ratio < 1) or slowed (ratio > 1). This leads to the weird
effect that changing the screen ratio by plugging a new monitor changes the
speed of the touchpad.
Use a different algorithm: calculate the physical movement on the device, map
that to the same-ish distance on the screen, then convert that back into a
device-specific vector. This way we get the same mapping regardless of the
current screen dimensions.
Since the pointer accel code doesn't take device resolution into account, make
sure we apply our crazy mapping before we accelerate. This way we accelerate
resolution-independent.

The server is leaking a pixmap (created by CreateDefaultStipple()) on
reset. The leak is caused by some X Server graphics contexts not being
freed on reset by the machine independent cursor code in the server,
which in turn is caused by the cursor cleanup code
(miSpriteDeviceCursorCleanup()) not being called.
Ensures the DeviceCursorCleanup() function is called when the associated

Whenever the master changes, push the locked modifier state to the attached
slave devices, then update the indicators. This way, when NumLock or CapsLock
are hit on any device, the LED will light up on all devices. Likewise, a new
keyboard attached to a master device will light up with the correct
indicators.
The indicators are handled per-keyboard, depending on the layout, i.e. if one
keyboard has grp_led:num set, the NumLock LED won't light up on that keyboard.

If there is a selection left over from a previous execution of the
main loop, and that selection has privates allocated for it, the X
server will crash. This is because dixResetPrivates() resets the
privates refcounts to zero without accounting for the reference held
by the selection object. When the selection is then deleted in
InitSelections() after the call to dixResetPrivates(), the refcount
for its privates type goes negative and bad things happen.
To fix this, we should delete any existing selections before calling
dixResetPrivates(). This will properly release the selection's
privates and avoid the crash.
A more thorough description of the problem and a test case to
reproduce the crash is available at a previous mail:
"Negative Selection devPrivates refcount?"
