Devices that send motion events with valuators other than x/y get core
motion events with unchanged x/y coordinates. This confuses some

If the DeviceEvent does not have the x/y valuators set, return BadMatch on
core conversion, thus skipping the event altogether.

A window with either dimension > 32767 can be positioned such that
coordinates > 32767 are visible on the screen. Attempts to draw to
those pixels will generate coordinates wrapped around to negative
values.
The optimized clipping macro, 'isClipped', in fbbits.h, computes
clipping in window space rather than screen space using int16 values,
and so it too has coordinates wrapped around to negative values and
hence ends up accepting the wrapped drawing coordinates.
Two possible fixes for this problem
1) Detect wrapped region coordinates and clip those to 32767.
2) Detect negative incoming coordinates and reject those
This patch takes the second approach as it is much shorter, simply
detecting when either X or Y incoming coordinate is negative, which
can never be 'within' any drawable.

A simple hack to accommodate various EDID who have detailed modes that
exceed the EDID's max pixel clock. The pixel clock is only defined in
units of 10MHz and often appears as the maximum pixel code of the
detailed modes, rounded to the nearest 10MHz. Adjusting the max_clock to
include an extra 5MHz prevents the parser from rejecting the detailed
modes.
The kernel uses the same fuzz and by including it in X we can use the
same modes in X as for the console.
Fixes:
Bug 23833 - X uses different refresh rate to that set by kernel module
https://bugs.freedesktop.org/show_bug.cgi?id=23833
In the future, we will want to try harder to keep the KMS modes but at
the same time we need to apply the restrictions as specified by the
user's configuration, and need to fill in modes for fullscreen games on
fixed-mode panels.

commit 1432785839
xkb: release XTEST pointer buttons on physical releases. (#28808)
revealed a bug with the XTEST/PointerKeys interaction.
Events resulting from PointerKeys are injected into the event processing
stream, not appended to the event queue. The events generated for the fake
button press include a DeviceChangedEvent (DCE), a raw button event and the
button event itself. The DCE causes the master to switch classes to the
attached XTEST pointer device.
Once the fake button is processed, normal event processing continues with
events in the EQ. The master still contains the XTEST classes, causing some
events to be dropped if e.g. the number of valuators of the event in the
queue exceeds the XTEST device's number of valuators.
Example: the EQ contains the following events, processed one-by-one, left to
right.
[DCE (dev)][Btn down][Btn up][Motion][Motion][...]
^ XkbFakeDeviceButton injects [DCE (XTEST)][Btn up]
Thus the event sequence processed looks like this:
[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][Motion][Motion][...]
The first DCE causes the master to switch to the device. The button up event
injects a DCE to the XTEST device, causing the following Motion events to be
processed with the master still being on XTEST classes.
This patch post-fixes the injected event sequence with a DCE to restore the
classes of the original slave device, resulting in an event sequence like
this:
[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][DCE (dev)][Motion][Motion]
Note that this is a simplified description. The event sequence injected by
the PointerKeys code is injected for the master device only and the matching
slave device that caused the injection has already finished processing on
the slave. Furthermore, the injection happens as part of the the XKB layer,
before the unwrapping of the processInputProc takes us into the DIX where
the DCE is actually handled.
Bug reproducible with a device that reports more than 2 valuators. Simply
cause button releases on the device and wait for a "too many valuators"
warning message.

Recursive alpha maps (where one picture's alpha map is set to a
picture with an external alpha map) would be all fine and dandy,
except for the case where the client constructs a loop. Detecting this
case when setting the alpha map values would be difficult as any time
an alpha map is set, the server would have to check for the looping
case.
Instead, a far simpler fix is to simply disallow recursive alpha maps
in the rendering code, the Render spec is ambiguous in this area and
allows us to to ignore the recursive case.

IsFramedWindow() is called from miPaintWindow() if the server has
been built with ROOTLESS defined, irrespective of if RootlessInit()
has ever been called, or not.
Add a check to IsFramedWindow() to check if rootlessWindowPrivateKey
has been registered (as a proxy for checking if the rootless extension
has been initialized) so we don't go on to try to use that key,
triggering an assert.
This bug exposes what appears to be a difference in opinion about
the rootless extension between XQuartz and XWin. XQuartz always
initializes the rootless extension, whereas XWin offers several modes
of operation, and the rootless extension is only used for one of them
That probably means that the all code under compile time guard for
ROOTLESS should be carefully checked that it doesn't also need to be
under a run-time guard
(I've reviewed the other ROOTLESS blocks in dix/events.c and

Change the damage extension reporter to queue up events after we chain
to the wrapped functions. Damage events are typically sent out after
the rendering happens anyway, since we submit batch buffers from the
flush callback chain and then flush client io buffers. Compositing
managers relie on this order, and there is no way we could reliably
provide damage events to clients before the rendering happens anyway.
By queueing up the damage events before the rendering happens, there's
a risk that the client io buffer may overflow and send the damage
events to the client before the driver has even seen the rendering
request. Reporting damage events after the rendering fixes this
corner case and better corresponds with how we expect this to work.
