defmin/defmax are screen coords and thus use a min-inclusive, max-exclusive
range. device axes ranges are inclusive, so bump the max up by one to get the
scaling right.
This fixes off-by-one coordinate errors if the coordinate matrix is used to
bind the device to a fraction of the screen. It introduces an off-by-one
scaling error in the device coordinate range, but since most devices have a
higher resolution than the screen (e.g. a Wacom I4 has 5080 dpi) the effect
of this should be limited.
This error manifests when we have numScreens > 1, as the scaling from
desktop size back to screen size drops one device unit.

Obsolete since 4bc2761ad5. This struct
existed so copying a passive grab could be simply done by
activeGrab = *grab
and thus have a copy of the GrabPtr we'd get from various sources but still
be able to check device->grab for NULL.
Since 4bc2761 activeGrab is a pointer itself and points to the same memory
as grabinfo->grab, leaving us with the potential of dangling pointers if
either calls FreeGrab() and doesn't reset the other one.
There is no reader of activeGrab anyway, so simply removing it is
sufficient.
Note: field is merely renamed to keep the ABI. Should be removed in the
future.

If we're about to abort, we're already in the signal handler and cannot call

Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.
This is largely backwards-compatible, hence the input ABI minor bump only.
Drivers we care about either return BadValue on a mode that's not

here is vmmouse, which currently ignores it and would not reset anything.

f3410b97cf introduced a regression on server

are usually still down) sending a raw event will segfault the server. The
the root windows are set to NULL before calling CloseDownDevices().
Avoid this by disabling all devices first when shutting down. Disabled
devices won't send events anymore.
Master keyboards must be disabled first, otherwise disabling the pointer
will trigger DisableDevice(keyboard) and the keyboard is removed from the
inputInfo.devices list and moved to inputInfo.off_devices. A regular loop

These structs will be used to store touch-related data, events and
information.
Drivers must call InitTouchClassDeviceStruct to set up a multi-touch capable
device.
Touchpoints for the DDX and the DIX are handled separately - touchpoints
submitted by the driver/DDX will be stored in the DDXTouchPointInfoRec. Once
the touchpoints are processed by the DIX, new TouchPointInfoRecs are created
and stored. This process is already used for pointer events with the
last.valuators field.
Note that this patch does not actually add the generation of touch events,
only the required structs.
TouchListeners are (future) recipients of touch or emulated pointer events.
Each listener is in a state, depending which event they have already
received. The type of listener defines how the listener got to be one.

miPointerSetPosition traditionally took coordinates on a per-screen basis,
triggering a screen switch when these went out-of-bounds. For absolute
devices, this prevented screen crossing in the negative x/y direction.
This patch changes the event generation patch to handle screen coordinates
in a desktop range (i.e. all screens together). Screen switches are
triggered when these coordinates are not on the current screen.
This unifies the pointer behaviour of single ScreenRec multihead and
multiple ScreenRecs multihead in that the cursor by default moves about the
whole screen rather than be confined to one single screen. The
transformation matrix may then be used to actually confine the cursor to the
screen again.
Note: fill_pointer_events has to deal with several different coordinate
systems. Make sure you read the comment before trying to understand the code.

For scroll wheel support, we used to send buttons 4/5 and 6/7 for
horizontal/vertical positive/negative scroll events. For touchpads, we
really want more fine-grained scroll values. GetPointerEvents now
accepts both old-school scroll button presses, and new-style scroll axis
events, while emitting both types of events to support both old and new
clients.
This works with the new XIScrollClass to mark axes as scrolling axes.
Drivers mark any valuators that send scroll events with SetScrollValuator.
(Currently missing: the XIDeviceChangeEvent being sent when a driver changes
a scroll axis at run-time. This can be added later.)
Note: the SCROLL_TYPE enums are intentionally different values to the XI2
proto values to avoid copy/overlapping range bugs.
