Subject: [PATCH] backends: Always enable tap-to-click/drag on opaque Wacom
tablets
Touch-wise, those are essentially giant touchpads, but have no buttons
associated to the "touchpad" device (There may be pad buttons, but
those are not mouse buttons).
Without tap-to-click/drag, touch in those devices is somewhat useless
out of the box. Have them always enable these features, despite the
setting.

Subject: [PATCH] backends: Check both input settings and mapper for tablet
monitors
The upper layers (OSDs basically) want to know the monitor that a
tablet is currently assigned to, not the monitor just as configured
through settings.
This broke proper OSD positioning for display-attached tablets since
commit 87858a4e01d9, as the MetaInputMapper kicks in precisely when
there is no configured monitor for the given device.
Consulting both about the assigned output will make OSDs pop up
again in the right place.

Subject: [PATCH] backends/x11: Observe multiple pad mode switch buttons in a
group
Some tablets like the Cintiq 24HDT have several mode switch buttons
per group. Those are meant to jump straight to a given mode, however
we just handle cycling across modes (as most other tablets have a
single mode switch button per group).
So spice up the mode switch handling so we handle multiple mode
switch buttons, assigning each of them a mode. If the device only
has one mode switch button, we do the old-fashioned cycling.

Subject: [PATCH] core: Let pad mode switch events always go through
MetaInputSettings
We used to inhibit all pad actions while the OSD is shown, but one we
would actually want to handle are mode switches while the OSD is open.
So it has an opportunity to catch up to the mode switch.
This lets MetaInputSettings reflect the mode switch (eg. when querying
action labels), so the OSD has an opportunity to update the current
actions.

Subject: [PATCH] events: Sync pending pointer events without a window
Mutter issues a synchronous grab on the pointer for unfocused client
windows to be able to catch the button events first and raise/focus
client windows accordingly.
When there is a synchronous grab in effect, all events are queued until
the grabbing client releases the event queue as it processes the events.
Mutter does release the events in its event handler function but does so
only if it is able to find the window matching the event. If the window
is a shell widget, that matching may fail and therefore Mutter will not
release the events, hence causing a freeze in pointer events delivery.
To avoid the issue, make sure we sync the pointer events in case we
can't find a matching window.

Subject: [PATCH] iconcache: Avoid xrender picture formats when creating cairo
surface
If an application provides its window icon via wmhints, then mutter
loads the pixmap specified by the application into a cairo xlib surface. When
creating the surface it specifies the visual, indirectly, via an XRender
picture format.
This is suboptimal, since XRender picture formats don't have a way to specify
16bpp depth, which an application may be using.
In particular, applications are likely to use 16bpp depth pixmaps for their
icons, if the video card offers a 16bpp framebuffer/root window.
This commit drops the XRender middleman, and just tells cairo a visual to use
directly.

Subject: [PATCH 1/2] workspace: Focus only ancestors that are focusable
When destroying a window that has a parent, we initially try to focus one of
its ancestors. However if no ancestor can be focused, then we should instead
focus the default focus window instead of trying to request focus for a window
that can't get focus anyways.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/308

Subject: [PATCH] x11: Check wacom button flags to determine whether button is
mode switch
Checking the leds is not really accurate, since some devices have mode
switch buttons without leds. Check in the button flags whether they are
mode switch buttons for any of ring/ring2/strip/strip2, and return the
appropriate group.

Subject: [PATCH 2/2] monitor-manager/xrandr: Create dummy screen sized monitor
if no RANDR
When there is no RANDR support enabled in the X server, we wont get
notified of any monitors, resulting in mutter believing we're being
headless. To get at least something working, although with no way
configuration ability, lets pretend the whole screen is just a single
monitor with a single output, crtc and mode.

an unmanaged
If something (i.e. gnome-shell or an extension) tries to activate an unmanaged
window, we should warn about this and avoid to perform further actions as this
could lead to a crash of mutter, since the window has not valid flags (like
workspace) set anymore at this stage.

Subject: [PATCH 03/12] cogl: Replace ANGLE with GLES3 and NV framebuffer_blit
ANGLE extensions are only provided by Google's Almost Native Graphics Layer
Engine (ANGLE) implementation. Therefore they do not seem too useful for
Mutter.
The reason to drop GL_ANGLE_framebuffer_blit support is that it has more
limitations compared to the glBlitFramebuffer in GL_EXT_framebuffer_blit,
GL_NV_framebuffer_bit, OpenGL 3.0 and OpenGL ES 3.0. Most importantly, the
ANGLE version cannot flip the image while copying, which limits
_cogl_blit_framebuffer to only off-screen <-> off-screen copies. Follow-up work
will need off-screen <-> on-screen copies.
Instead of adding yet more capability flags to Cogl, dropping ANGLE support
seems appropriate.
The NV extension is added to the list of glBlitFramebuffer providers because it
provides the same support as ANGLE and more.
Likewise OpenGL ES 3.0 is added to the list of glBlitFramebuffer providers
because e.g. Mesa GLES implementation usually provides it and that makes it
widely available, again surpassing the ANGLE supported features.
Follow-up patches will lift some of the Cogl assumptions of what
glBlitFramebuffer cannot do.

Subject: [PATCH 04/12] cogl: Relax formats on glBlitFramebuffer
Depends on: "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
As a possible ANGLE implementation is not longer limiting the pixel format
matching, lift the requirement of having the same pixel format.
We still cannot do a premult <-> non-premult conversion during a blit, so guard
against that.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer if the formats do not
match exactly.

Subject: [PATCH 05/12] cogl: Allow glBlitFramebuffer between
onscreen/offscreen
Depends on "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
Allow blitting between onscreen and offscreen framebuffers by doing the y-flip
as necessary. This was not possible with ANGLE, but now with ANGLE gone,
glBlitFramebuffer supports flipping the copied image.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer.

Subject: [PATCH 07/12] cogl: Expose cogl_blit_framebuffer
The function will be used in copying from a primary GPU framebuffer to a
secondary GPU framebuffer using the primary GPU specifically when the
secondary GPU is not render-capable.
To allow falling back in case glBlitFramebuffer cannot be used, add boolean
return value, and GError argument for debugging purposes.

Subject: [PATCH 08/12] clutter/stage-view: Use cogl_blit_framebuffer() for

If there is no transformation, use `cogl_blit_framebuffer()` as a
shortcut in `clutter_stage_view_blit_offscreen()`, that dramatically
improves performance when using a shadow framebuffer.

Subject: [PATCH 09/12] clutter/stage-view: Ignore clipping rectangle for
offscreen blit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In `clutter_stage_view_blit_offscreen()`, the given clipping rectangle
is in “view” coordinates whereas we intend to copy the whole actual
framebuffer, meaning that we cannot use the clipping rectangle.
Use the actual framebuffer size, starting at (0, 0) instead.
That fixes the issue with partial repainting with shadow framebuffer
when fractional scaling is enabled.

Subject: [PATCH 11/12] clutter/stage-view: Separate offscreen and shadowfb
Previously, we would use a single offscreen framebuffer for both
transformations and when a shadow framebuffer should be used, but that
can be dreadfully slow when using software rendering with a discrete GPU
due to bandwidth limitations.
Keep the offscreen framebuffer for transformations only and add another
intermediate shadow framebuffer used as a copy of the onscreen
framebuffer.

Keep the previous offscreen framebuffer is as an intermediate
framebuffer for transformations only.
This way, we can apply transformations between in-memory framebuffers
prior to blit the result to screen, and achieve acceptable performance
even with software rendering on discrete GPU.

Subject: [PATCH 3/3] idle-monitor: Reset timeout before firing watch
The watch might be removed during firing, meaning the source is
destroyed after returning. Avoid use-after-free by unsetting the timeout
before firing. Returning G_SOURCE_CONTINUE in that case is harmless, as
source is destroyed.

Instead of overriding the existing mode with the preferred mode of the monitor,
use the one already configured. Also use the MetaMonitor API for deriving the

Subject: [PATCH 2/2] monitor-manager: Don't try to derive current config on
non-X11
This commit also reworks the initial config state reading some. Appart from
avoiding trying to inherit from backends where it doesn't make sense, it does
the following changes:
* Replace the name "initial" with "inherited", as the initial config in the
context of monitor management is the one used initialization. E.g. if there is
a applicable configuration in monitors.xml, the initial config is taken from
there.
* Don't make "_create_()" functions have side effects. Previously
meta_monitor_config_manager_create_initial() also set state on the config
manager object. Instead, add a meta_monitor_config_manager_ensure_inherited()
and meta_monitor_manager_get_inherited_config() function to make things more
explicit.
* Don't recreate "is-applicable" logic, just use the existing helper.

Subject: [PATCH 2/2] x11: Limit touch replay pointer events to when replaying
When a touch sequence was rejected, the emulated pointer events would be
replayed with old timestamps. This caused issues with grabs as they
would be ignored due to being too old. This was mitigated by making sure
device event timestamps never travelled back in time by tampering with
any event that had a timestamp seemingly in the past.
This failed when the most recent timestamp that had been received were
much older than the timestamp of the new event. This could for example
happen when a session was left not interacted with for 40+ days or so;
when interacted with again, as any new timestamp would according to
XSERVER_TIME_IS_BEFORE() still be in the past compared to the "most
recent" one. The effect is that we'd always use the `latest_evtime` for
all new device events without ever updating it.
The end result of this was that passive grabs would become active when
interacted with, but would then newer be released, as the timestamps to
XIAllowEvents() would out of date, resulting in the desktop effectively
freezing, as the Shell would have an active pointer grab.
To avoid the situation where we get stuck with an old `latest_evtime`
timestamp, limit the tampering with device event timestamp to 1) only
pointer events, and 2) only during the replay sequence. The second part
is implemented by sending an asynchronous message via the X server after
rejecting a touch sequence, only potentially tampering with the device
event timestamps until the reply. This should avoid the stuck timestamp
as in those situations, we'll always have a relatively up to date
`latest_evtime` meaning XSERVER_TIME_IS_BEFORE() will not get confused.
