Terms:
dev->last.valuator[] is the last value given to us by the driver
dev->valuator.axisVal[] is the last value sent to the client
dev->last.scroll[] is the abs value of the scroll axis as given by the driver,
used for button emulation calculation (and the remainder)
This function updates the device's last.valuator state based on the current
master axis state. This way, relative motion continues fluidly when switching
between devices. Before mouse 2 comes into effect, it's valuator state is
updated to wherever the pointer currently is so the relative event applies on
top of that.
This can only work for x/y axes, all other axes aren't guaranteed to have the
same meaning and/or may not be present:
- xtest device: no valuator 2
- mouse: valuator 2 is horizontal scroll axis
- tablet: valuator 2 is pressure
Scaling the current value from the pressure range into the range for
horizontal scrolling makes no sense. And it causes scroll jumps:
- scroll down, last.valuator == axisVal == 20
- xdotool click 1, the XTest device doesn't have that valuator
- scroll up
- updateSlaveDeviceCoords reset last.valuator to 0 (axisVal == 20)
- DeviceClassesChangedEvent includes value 20 for the axis
- event is processed, last.value changes from 0 to -1
- axisVal is updated to -1, causing a jump of -21
The same applies when we switch from tablet to mouse wheel if the pressure
value is 0 on proximity out (basically guaranteed). So let's drop this code
altogether and only leave the scaling for the relative x/y motion.

We cover all Render ops under the "blend" group, so when we're doing
the cross products of some formats for the masking operation, skip
most of the ops (covering just zero, one, and src/dst alpha blend
factors along with a definitely non-glamor-accelerated one) .

systemd-logind since version 234 (released 2017-07-12) supports being
restarted without losing state [1]. From the systemd NEWS file [2]:
* systemd-logind may now be restarted without losing state. It stores
the file descriptors for devices it manages in the system manager
using the FDSTORE= mechanism. Please note that further changes in
other components may be required to make use of this (for example
Xorg has code to listen for stops of systemd-logind and terminate
itself when logind is stopped or restarted, in order to avoid using
stale file descriptors for graphical devices, which is now
counterproductive and must be reverted in order for restarts of
systemd-logind to be safe. See
https://cgit.freedesktop.org/xorg/xserver/commit/?id=dc48bd653c7e101.)

xwl_present_cleanup frees the struct xwl_present_window memory,

This is maybe one more comparison, but it catches FullyObscured windows

allows for paintable but unmapped windows, which will have non-empty
clipList.
If `_glamor_create_tex()` fails to allocate the FBO because of
GL_OUT_OF_MEMORY error, the `pixmap_priv->fbo` is NULL.
However, `glamor_get_pixmap_texture()` doesn't actually check whether
the `pixmap_priv->fbo` is NULL and will segfault with a NULL pointer
dereference trying to access the `pixmap_priv->fbo->tex`.

We currently support two modes of operation for RW PBO buffers: one
that allocates a pack buffer with GL memory and one that uses system
memory when the former is not supported.
Since allocation with system memory is less likely to fail, add a
fallback to system memory when GL memory failed instead of bailing
out.

When uploading a picture to a texture, glamor_upload_picture_to_texture
calls glamor_pixmap_ensure_fbo to ensure that there is backing FBO.
The FBO will be allocated if the picture's drawable pixmap does not have
one already, which can fail when there is no GL memory left.
glamor_upload_picture_to_texture checks that the call succeeded and will
enter the failure path if it did not. However, unlike many other
functions in glamor, this one has ret set to TRUE initially, so it needs
to be set to FALSE when a failure happens.
Otherwise, the error is not propagated and the failure path return TRUE.
This leads to a fault when trying to access the FBO pointer later on.

Normally, the X server infers the initial screen size based on any
connected outputs. However, if no outputs are connected, the X server
picks a default screen size of 1024 x 768. This option overrides the
default screen size to use when no outputs are connected. In contrast
to the "Virtual" Display SubSection entry, which applies unconditionally,
"NoOutputInitialSize" is only used if no outputs are detected when the
X server starts.
Parse this option in the new exported helper function
xf86AssignNoOutputInitialSize(), so that other XFree86 loadable drivers
can use it, even if they don't use xf86InitialConfiguration().

The VGA arbiter controls the PCI bus' routing of legacy VGA resources,
specifically the video memory aperture at 0xa0000-0xb0000 (640k should
be etc.) and a handful of I/O ports. Since 128k is far too small for a
real framebuffer these days, every driver instead maps a linear version
of VRAM through the PCI BAR. And no DRI2 drivers ever need I/O port
access, because all operations they might be used for (legacy VGA CRTC
setup, mostly) happen on the kernel side.
In other words, this just works, and we can stop breaking it.

Indeed, that PCI ID is missing from i965_pci_ids. Adding it fixed the issue
and allowed the system to work with i965_dri under modesetting.
