A sync grab is the owner once it gets events. If it doesn't replay the
event it will get all events from this touch, equivalent to accepting it.
If the touch has ended before XAllowEvents() is called, we also now need to
send the TouchEnd event and clean-up since we won't see anything more from
this touch.
Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
If a device is frozen in results to a grab, we need to enqueue the events.
This makes things complicated, and hard to follow since touch events are now
replayed in the history, pushed into EnqueueEvent, then replayed later
during PlayReleasedEvents in response to an XAllowEvents.
While the device is frozen, no touch events are processed, so if there is a
touch client with ownership mask _below_ the grab this will delay the
delivery and potentially screw gesture recognition. However, this is the
behaviour we have already anyway if the top-most client is a sync pgrab or
there is a sync grab active on the device when the TouchBegin was generated.
(also note, such a client would only reliably work in case of ReplayPointer
anyway)

If the device is currently grabbed as the result of a passive grab
activating, do not prepend that grab to the listeners (unlike active grabs).
Otherwise, a client with a passive pointer grab will prevent touch grabs
from activating higher up in the window stack.

InitPointerClassDeviceStruct/InitKeyboardDeviceStruct allocate a

InitFocusClassDeviceStruct or InitProximityClassDeviceStruct beforehand,
the previously allocated class is overwritten, leaking the memory.
Neither takes a parameter other than the device, so we can simply skip
initialising it if we already have one.

Absolute devices may send relative events depending on the mode (synaptics
by default, wacom per option). The relative events are added to the previous
position, converted into device coordinates and then scaled into desktop
coordinates for pointer movement.
Because the device range must be mapped into the desktop coordinate range,
this results in uneven scaling depending dimensions, e.g. on a setup with
width == 2 * height, a relative movement of 10/10 in device coordinates
results in a cursor movement of 20/10 (+ acceleration)
Other commonly user-visible results:
* the touchpad changing acceleration once an external monitor as added.
* drawing a circle on a wacom tablet in relative mode gives an ellipsis in
the same ratio as the desktop dimensions.
Solution: pre-scale the incoming relative x/y coordinates by width/height
ratio of the total desktop size. Then add them to the previous
coordinates and scale back with the previous mapping, which will undo the
pre-scaling and give us the right movement.

Disabling a XTest device followed by an XTest API call crashes the server.
This could be fixed elsewhere but disabled devices must not send events
anyway. The use-case for disabled XTest devices is somewhat limited, so
simply disallow disabling the devices.

These functions are already declared in <X11/fonts/fontproto.h>.
Redeclaring them just for _X_EXPORT causes tons of warnings throughout
xserver, but they need to be declared somewhere to be picked up by
sdksyms.sh. Doing so in a private header limits the warnings to
sdksyms.c; fixing those as well would require changes to fontsproto.

The allocated TouchListener array may fall short by 1 if hitting the worst case
situation where there's an active grab, passive grabs on each window in the
sprite trace and event selection for touch in one of the windows. This may lead
to memory corruptions as the array is overflown.

A disabled device doesn't have a sprite (less so a sprite->win) and triggers
a NULL-pointer dereference on shutdown when all active grabs are released as
part of the cleanup.
Fix this by checking for sprite being non-null and setting the focus window
to the NullWindow if it is. The rest of the patch just attempts to make
things more readable.

If the device is disabled, the sprite window is NULL and dereferencing
crashes the server.
This is only triggered for XI 1.x grabs (ProcXGrabDevice) as XI2 grabs would
trigger another code path, creating a sprite for the disabled device as if
detaching it (which is wrong and fixed with this patch too).
Grabbing a disabled device doesn't make sense as it won't send events
anyway. However, the protocol specs do not prohibit it, so we need to keep
it working.
Luckily, oldWin is only used for focus out events, which aren't necessary
given that the device is disabled.

Scale_to_desktop() converts ABS events from device coordinates
to screen coordinates:
[dev_X_min, dev_X_max] -> [screen_X_min, screen_X_max]
[dev_Y_min, dev_Y_max] -> [screen_Y_min, screen_Y_max]
An edge ABS event with X = dev_X_max (e.g., generated from the
edge of a touchscreen) will be converted to have screen X value
= screen_X_max, which, however, will be filterd out when xserver
tries to find proper Window to receive the event, because the
range check for a Window to receive events is
window_X_min <= event_screen_X < window_X_max
Events with event_screen_X = screen_X_max will fail the test get
and rejected by the Window.
To fix this, we change the device to screen coordinates mapping to
[dev_X_min, dev_X_max] -> [screen_X_min, screen_X_max-1]
[dev_Y_min, dev_Y_max] -> [screen_Y_min, screen_Y_max-1]

The property handler is registered after setting the property, so
dev->transform remains as all-zeros. That causes pixman_f_transform_invert()
to fail (in transformAbsolute()) and invert remains as garbage. This
may then cause a cursor jump to 0,0.
Since the axes are not yet initialized here and we need to allow for drivers
changing the matrix, we cannot use the property handler for matrix
initialization, essentially duplicating the code.

Forwarding proxies like sshd will appear to be local, even though they
aren't really. This leads to weird behaviour for extensions that truly
require running under the same OS services as the client, like MIT-SHM
and DRI2.
Add two new legal values for the initial connection's byteOrder field,
'r' and 'R'. These act like 'l' and 'B' respectively, but have the side
effect of forcing the client to be treated as non-local. Forwarding
proxies should attempt to munge the first packet of the connection
accordingly; older servers will reject connections thusly munged, so the
proxy should fall back to passthrough if the munged connection attempt
fails.

In WarpPointer calls, we get input in screen coordinates. They must be
scaled to device coordinates, and then back to screen coordinates for screen
crossing and root coordinates in events.
The rounding errors introduced (and clipping in core/XI 1.x events) can lead
to the actual position being different to the requested input coordinates.
e.g. 200 scales to 199.9999, truncated to 199 in the event.
Avoid this by simply overwriting the scaled screen coordinates with the
input coordinates for the POINTER_SCREEN case.

If a device has smooth scrolling axes, but submits scroll button events, we
convert those to motion events and update the valuators. For legacy button
events, the valuator mask is likely unset though, causing
add_to_scroll_valuator() to return early, leaving us with an empty mask.
That again skipped the rest of the code and no events were generated.
Fix it by making sure that the scroll valuator in the mask is at least
initialized to 0.
