Syncronized subsurfaces that call into `merge_pending_state` might
otherwise not create new destroy handlers, ending up with a invalid
handler ids, throwing errors and leaking.

It might be the case that handling an event induces the stream to
trigger completion, hence removing itself from the list. In that
case we would operate on the no longer valid list element to fetch
the next one.
Keep a pointer to the next element beforehand, so we can tiptoe
over streams that did remove themselves.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/869
The streams were only detached from MetaX11Display (and its event handling)
on completion. This is too much to expect, and those might be in some
circumstances replaced while operating.
Make those streams detach themselves on dispose(), so we don't trip into
freed memory later on when trying to dispatch unrelated X11 selection events.

Instead of doing a roundtrip to the X server before setting it, rely on
the previous value fetched before the configuration was sent over DBus.
This matches the argument check we already do elsewhere, and will allow
us to more easily add an additional condition to determine if underscan
is supported.

Midscene tracking was used at a time that some Cogl users
could call random OpenGL API without going through Cogl.
That is not allowed anymore, and certainly not done by
Mutter and GNOME Shell.
Remove midscene tracking from CoglFramebuffer.

CoglJournal tracks a few OpenGL states so that they can
be batch-applied if necessary. It also has a nice property
of allowing purely CPU-based glReadPixels() when the scene
is composed of simple rectangles.
However, the current journal implementation leaves various
other GL states out, such as dithering and the viewport.
In Clutter, that causes the journal to be flushed when
picking, touching the GPU when we didn't really need to.
Track the viewport of the framebuffer in the journal so that
we can avoid flushing the journal so often.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/402
CoglFramebuffer checks the passed buffer bits in order to
detect when the fast path (that uses the journal) should
be used.
However, it also modifies one of the buffer bits that is
checked for the fast path, meaning we never actually hit
the fast path on cogl_framebuffer_cleaf4f().
Check the depth and color buffer bits before modifying them.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/402
Previously picking was done on an int (x,y) to address a particular pixel.
While `int` was the minimum precision required, it was also an unnecessary
type conversion.
The callers (input events mainly) all provide float coordinates and the
internal picking calculations also have always used floats. So it was
inconsistent and unnecessary to drop to integer precision in between those.
ABI break: This changes the parameter types for public function
`clutter_stage_get_actor_at_pos`, but its documentation is already
sufficiently vague to not need changing.

This is an extremely straightforward and minimalistic port of
CoglVector APIs to the corresponding Graphene APIs.
Make ClutterPlane use graphene_vec3_t internally too, for the
simplest purpose of keeping the patch focused.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
As the first step into removing Cogl types that are covered by
Graphene, remove CoglEuler and replace it by graphene_euler_t.
This is a mostly straightforward replacement, except that the
naming conventions changed a bit. Cogl uses "heading" for the
Y axis, "pitch" for the X axis, and "roll" for the Z axis, and
graphene uses the axis themselves. That means the 1st and 2nd
arguments need to be swapped.
Also adapt the matrix stack to store a graphene_euler_t in the
rotation node -- that simplifies the code a bit as well.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Mutter requires Clutter, which requires Cogl. That means
Clutter requires all Cogl dependencies, and Mutter requires
all Clutter dependencies as well.
However, currently, Clutter does not pull in its dependencies,
which means we need to link against Cogl manually.
Add Clutter dependencies to declare_dependency() so that the
graphene dependency only needs to be declared once, for Cogl,
and pulled together.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Graphene is a small library with data types and APIs
specially crafted to computer graphics. It contains
performant implementations of matrices, vectors, points
and rotation tools. It is performance because, among
other reasons, it uses vectorized processor commands
to compute various operations.
Add Graphene dependency to Mutter.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Graphene uses C99 and includes stdbool.h, which adds a
new 'bool' type. Clutter has an a11y test that names a
variable as 'bool' too, and they do not play well together.
Rename this variable to boolean.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
This is a deprecated property that is not used anywhere
in the codebase. Not by GNOME Shell. Because it uses the
deprecated ClutterGeometry type, it's a good target for
cleaning up, given that ClutterGeometry will be dropped
later on.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/458
Fog is explicitly deprecated in favour of CoglSnippet API,
and in nowhere we are using this deprecated feature, which
means we can simply drop it without any sort of replacement.

Move out updating of various shapes (input, opaque, shape) indirectly
from X11 to the corresponding X11 sub types of MetaWindowActor and
MetaSurfaceActor.
Also move fullscreen window unredirection code with it. We want to
effectively do something similar for MetaCompositorServer, but it will
work differently enough not to share too much logic.
While it would have been nice to move things piece by piece, things were
too intertwined to make it feasible.
This has the side effect fixing accidentally and arbitrarily adding
server side shadow to Wayland surfaces.
