216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

Font initialization was split into two stages, the first was to set up
font privates with a call to ResetFontPrivateIndex, then much later
the call to InitFonts to set up all of the FPEs. Doing the full font
initialization before initializing the video drivers means that we can
move the call to ResetFontPrivateIndex inside InitFonts.

Patch 3ab6cd31cbdf8095b2948034fce5fb645422d8da fixed Xinerama
interactions with font servers by not putting clients to sleep
multiple times. However, it introduced additional changes dealing with
libXfont routine returning Suspended more than once for the same
request. This additional change was to abandon processing of the
current request and free the closure data by jumping to
'xinerama_sleep' in each of the functions.
Font library functions shouldn't return Suspended more than once,
except for ListFontsWithInfo, which produces multiple replies, and
thus ends up returning Suspended many times during processing.
With the jump to xinerama_sleep occurring after the first reply was
processed, the closure for the request was freed and future calls into
the ListFontsWithInfo callback resulted in dereferencing freed
memory.
This patch removes the added branches, reverting the code to its
previous behaviour, which permitted multiple Suspended returns and
simply waited for the client to be signaled again so that the callback
could continue processing the request.

The modesetting driver corrupts memory when used after a server regeneration
because not enough memory is allocated for its pixmap privates. This happens
because its call to dixRegisterScreenSpecificPrivateKey() does nothing because
key->initialized is still TRUE from the first server generation. However, the
key is not in the screen's linked list of screen-specific privates because
that's freed and reallocated during the server generation loop in dix_main().
Fix this by clearing key->initialized before CloseScreen and add a call to
dixFreeScreenSpecificPrivates() for GPU screens.
v2: Just set key->initialized to FALSE and move dixFreeScreenSpecificPrivates()
calls to after CloseScreen.
v3: Move dixFreeScreenSpecificPrivates() calls back to just before CloseScreen.

Make the maximum number of clients user configurable, either from the command
line or from xorg.conf
This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).
There is a limit size of 29 bits to be used to store both the client ID and
the X resources ID, so by reducing the number of clients allowed to connect to
the X server, the user can increase the number of X resources per client or
vice-versa.
Parts of this patch are based on a similar patch from Adam Jackson

One of the lacking features with output offloading was
that screen rotation didn't work at all.
This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.
When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.
v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.
This breaks ABI in two places.

Allows a mask to carry both accelerated and unaccelerated motion at the same
time.
This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
and DGA rely on device-specific unaccelerated data.
To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.
Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.
The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.

For two ScreenRecs abs pointer positioning was working fine, but touch events
stuck to the lower/right edge on any screen but the one with a 0/0 origin.
Cause is a missing offset by the screen coordinates, causing the root

Offset properly, just like we do for pointer events.

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.
