If a KMS device has the DRM_CAP_DUMB_PREFER_SHADOW and a software based
GL driver is used, always use a shadow fb. This will speed up read backs
in the llvmpipe OpenGL implementation, making blend operations faster.

DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
whatever version of libdrm is present. Mutter was blindly asserting it
supported whatever version that may be, even if it actually didn't.
With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.
Set the version as 2, which should be bumped only with the appropriate
version checks.

The Wacom Xorg driver assigns a serial number of 1 for any pad that doesn't
have a serial. libinput assigns 0. Just treat 1 as 0 here, there are no pens
with a real serial 1 anyway.

Typically, to stream the content of a window, we need a way to copy the
content of its window-actor into a buffer, transform relative input
coordinates to relative position within the window-actor and a mean to
get the window bounds within the buffer.
For this purpose, add a new GType interface `MetaScreenCastWindow` with
the methods needed for screen-cast window mode:
* meta_screen_cast_window_get_buffer_bounds()
* meta_screen_cast_window_get_frame_bounds()
* meta_screen_cast_window_transform_relative_position()
* meta_screen_cast_window_capture_into()
This interface is meant to be implemented by `MetaWindowActor` which has
access to all the necessary bits to implement them.

To be able to cast windows, which by definition can change in size
dynamically, we need a way to specify the video crop meta to adjust to
the window size whenever it changes.
Add VideoCrop support with a new optional hook `get_videocrop()` in the
`ScreenCastStreamSrcClass` which, if defined, can let the child specify
a rectangle for the video cropping area.

Switch-configs are only to be used in certain circumstances (see
meta_monitor_manager_can_switch_config()) so when ensuring
configuration and attempting to create a linear configuration, use the
linear configuration constructor function directly without going via the
switch config method, otherwise we might incorrectly fall back to the
fallback configuration (only enable primary monitor).
This is a regression introduced by 6267732bec.

Which eliminates the 1px jitter that was visible when dragging windows,
and eliminates the flickering that was visible when pushing the cursor
against the right/bottom edges of the screen.
If a display device (touchscreen, tablet with libwacom integration flags)
does not receive a monitor through settings. Delegate on the
MetaInputMapper so it receives a mapping through heuristics.
This object takes care of mapping absolute devices to monitors,
to do so it uses 3 heuristics, in this order of preference:
- If a device is known to be builtin, it's assigned to the
builtin monitor.
- If input device and monitor match sizes (with an error margin
of 5%)
- If input device name and monitor vendor/product in EDID match
somehow (from "full", through "partial", to just "vendor")
The most favorable outputs are then assigned to each device, making
sure not to assign two devices of the same kind to the same output.
This object replaces (and is mostly 1:1 with) GsdDeviceMapper in
g-s-d. That object would perform these same heuristics, and let
mutter indirectly know through settings changes. This object allows
doing the same in-process.
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.
In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.
Removing it means less code, less branches when running,
and one less config option to deal with.
This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

Externally setting the sync-to-vblank setting was a feature
added as a workaround to old Intel and ATI graphic cards, and
is not needed anymore. Furthermore, it doesn't make sense to
change it on a compositor whatsoever.
This commit removes all the ways to externally change this
setting, as well as the now unused API.

The nested stage tries to emulate how CRTCs are drawn, but fails to do
this when a stage view is scaled as it didn't adapt the viewport size
according to the stage view scale.

Add MUTTER_DEBUG_DUMMY_MONITORS_SPECS env variable support so that you can define
a ':' separated list of monitor specs in the form of WWWxHHH@RR that will be
available for configuring the nested mutter.
When calculating the logical monitor layout size given a scale, don't
risk precision loss by float to int casting, which could result in a too
small layout.

Modal ungrabs may be followed by other clients trying to grab themselves,
flush the connection so we ensure the right order of events on the Xserver
side.
An example of this is js/ui/modalDialog.js in gnome-shell, as the alt-F2
dialog may launch X11 clients trying to grab themselves, commit a40daa3c22
in gnome-shell handled the case and added a gdk_display_sync() call to
ensure no grab existed at the time of executing.
This commit aims to achieve the same built in MetaBackend. A full sync
seems excessive though, as we just need to make sure the server got the
messages queued before the other side tries to grab, a XFlush seems
sufficient for this.
The nested backend used the value from udev, meaning that one couldn't
configure the fake monitor if the laptop panel of the host was closed.
Avoid this annoyance by always having the nested backend claiming the
lid is open.
It wasn't implemented by any subclass, it's not provided by DRM either.
And even if a subclass were to have only a file available, it could read
it into a GBytes as well and just use `read_edid()`.
Found this while working on !269.
Because it is implemented and always on. By advertising this fact
the master clock is able to sync to the native refresh rate instead
of always using the fallback of 60.00Hz.

Add support for getting hardware presentation times from KMS (Wayland
sessions). Also implement cogl_get_clock_time which is required to compare
and judge the age of presentation timestamps.
For single monitor systems this is straightforward. For multi-monitor
systems though we have to choose a display to sync to. The compositor
already partially solves this for us in the case of only one display
updating because it will only use the subset of monitors that are
changing. In the case of multiple monitors consuming the same frame
concurrently however, we choose the fastest one (in use at the time).
Note however that we also need !73 to land in order to fully realize
multiple monitors running at full speed.
Use cogl_framebuffer_read_pixels_into_bitmap () instead of
glReadPixels () for the CPU copy path in multi-GPU support.
The cogl function employs several tricks to make the read-pixels as fast
as possible and does the y-flip as necessary. This should make the copy
more performant over all kinds of hardware.
This is expected to be used on virtual outputs (e.g. DisplayLink USB
docks and monitors) foremost, where the dumb buffer memory is just
regular system memory. If the dumb buffer memory is somehow slow, like
residing in discrete VRAM or having an unexpected caching mode, it may
be possible for the cogl function perform worse because it might do the
y-flip in-place in the dumb buffer. Hopefully that does not happen in
any practical scenario.
Calling meta_renderer_native_gles3_read_pixels () here was conceptually
wrong to begin with because it was done with the Cogl GL context of the
primary GPU, not on the GL ES 3 context of a secondary GPU. However,
due eglBindAPI being a no-op in Mesa and the glReadPixels () arguments
being compatible, it worked.
This patch adds a pixel format conversion table between DRM and Cogl
formats. It contains more formats than absolutely necessary and the
texture components field which is currently unused for completeness. See
Mutter issue #323. Making the table more complete documents better how
the pixel formats actually map so that posterity should be less likely
to be confused. This table could be shared with
shm_buffer_get_cogl_pixel_format () as well, but not with
meta_wayland_dma_buf_buffer_attach ().
On HP ProBook 4520s laptop (Mesa DRI Intel(R) Ironlake Mobile, Mesa
18.0.5), without this patch copy_shared_framebuffer_cpu () for a
DisplayLink output takes 5 seconds with a 1080p frame. Obviously that
makes Mutter and gnome-shell completely unusable. With this patch, that
function takes 13-18 ms which makes it usable if not fluent.
On Intel i7-4790 (Mesa DRI Intel(R) Haswell Desktop) machine, this patch
makes no significant difference (the copy takes 4-5 ms).
The format will be needed in a following commit in the CPU copy path
which stops hardcoding another format and starts using the format the
dumb FB was created with.
Change the callers of init_dumb_fb () to use DRM format codes. DRM and
GBM format codes are identical, but since this is about dumb buffers,
DRM formats fit better.
The header /usr/include/gbm.h installed by Mesa says:
* The FourCC format codes are taken from the drm_fourcc.h definition, and
* re-namespaced. New GBM formats must not be added, unless they are
* identical ports from drm_fourcc.
That refers to the GBM_FORMAT_* codes.
Virtual keyboard and pointer are freed on session close, but the
virtual touchscreen isn't.
Avoid a leak by freeing the virtual touchscreen along with the rest of
virtual devices.
We were using the connector_id for the winsys_id, but different
devices could have connectors with the same id. Since we use
winsys_id to uniquely identify outputs, use both the connector
id and the device id to avoid having outputs with the same id.
Python is not guaranteed to be installed in /usr/bin. This is especially
true for *BSD systems which don't consider Python as an integral part of
their systems.
Don't schedule redraws when being headless; there is nothing to draw so
don't attempt to draw. This also makes a flaky test become non-flaky, as
it previously spuriously got warnings due to windows being "painted"
when headless but lacking frame timings, as nothing was actually
painted.

The empty MetaStage was in meta-stage-private.h for no reason, so lets
move it to the C file. This makes it pointless to have a private

_MetaStage.
