CoglMatrix.get_array() returns the column-major CoglMatrix itself,
since the first fields of the matrix is effectively an array of
floats, and we can just pretend it is. Of course, it basically
ignores any C-specific type checking.
WIP
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.

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.

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.

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.

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.

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.

Meson 0.50.0 made passing an absolute path to install_headers()'
subdir keyword a fatal error. This means we have to track both
relative (to includedir) paths for header subdirs and absolute
paths for generated headers now :-(

If an intersection is empty, the (x, y) coordinates are undefined, so
just use the work area and in-progress constrained window rect when
sliding according to the SLIDE_X or SLIDE_Y custom placement rule.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/496
When check_only is TRUE, the constraint should not be applied, just
checked. We failed to comply here when a placed transient window was
to be moved together with its parent, updating the window position
directly even if check_only was TRUE.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/496
If a client maps a persistent popup with a placement rule, then resizes
the parent window so that the popup ends up outside of the parent,
unmanage the popup and log a warning about the client being buggy.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/496
When a parent window is moved, attached windows (attached modal dialogs
or popups) is moved with it. This is problematic when such a window
hasn't been shown yet (e.g. a popup that has been configured but not
shown), as it'll mean we try to constrain an empty window. Avoid this
issue by not trying to auto-move empty windows.
