e0944b6097 backend: Don't pull generated headers (indirectly)
Use a typedef for MetaRemoteDesktop, so tests poking MetaBackend don't
indirectly depend upon generated headers. This is arguably a code fix
for a build system bug.

6db7d8f830 backend: Add a backend release function
Mutter still relies heavily on singletons such as its MetaBackend.

For that, the backend implementation has a meta_init_backend() function
which is called at startup from meta_init(), which creates the desired
backend and sets the singleton which is returned by meta_get_backend().

Unfortunately, that means that the backend is never actually freed, and
all the code from the backend finalize function never actually get
called.

Add a meta_release_backend() to free the backend singleton.

c956193d09 input-settings: Disconnect device signals on dispose
The input settings constructor installs callback functions on device
added/remove and tool-changed.

However, on dispose, those signals are not disconnected, meaning that on
teardown, once the devices get removed eventually, the callback will
still fire and call the callback with freed data, causing a crash.

Make sure we clear the signals on devices on dispose, to avoid the crash
on teardown.

9e1004da0c cogl/matrix-stack: Use graphene APIs
This one is a bit tricky. The tl;dr; is that switching from right-hand
multiplication to left-hand multiplication required applying the stack
from left to root. This actually allowed simplifying the code a bit,
since CoglMatrixEntry only stores a pointer to its parent, and that's
all we need to know for left-hand multiplication.

f9d1b7ca58 clutter/clone: Use graphene APIs
This is another instance of graphene reversing the order of operations (see
the commit notes of how ClutterActor was ported.) The tl;dr; here is that,
in the CoglMatrix past, we used to do:

  (actor transforms) → scale

and now, it's the other way round:

  scale → (actor transforms)

due to changing from right-handed multiplications (CoglMatrix) to left-handed
ones (graphene_matrix_t).

2406f225a9 clutter/actor: Use graphene APIs
ClutterActor is a particularly heavy user of matrices, and
switching to graphene_matrix_* APIs means we had to change
the order of operations due to left-hand vs right-hand
differences.

When applying the actor transform, there are 2 main branches
that can be followed: the default transforms, and when a
custom transform is set.

To facilitate review, here's the table that I've made to
guide myself:

+--------------- Case 1: Default Transforms --------------+
|        CoglMatrix          |      graphene_matrix_t     |
+----------------------------+----------------------------+
| multiply (child transform) | translate (-pivot)         |
| translate (allocation)¹    | rotate_x (angle)           |
| translate (pivot)¹         | rotate_y (angle)           |
| translate (translation)¹   | rotate_z (angle)           |
| scale (sx, sy, sz)         | scale (sx, sy, sz)         |
| rotate_z (angle)           | translate (translation)¹   |
| rotate_y (angle)           | translate (pivot)¹         |
| rotate_x (angle)           | translate (allocation)¹    |
| translate (-pivot)         | multiply (child transform) |
+----------------------------+----------------------------+

¹ - these 3 translations are simplified as a single call
    to translate(allocation + pivot + translation)

+---------------- Case 2: Custom Transform ---------------+
|        CoglMatrix          |      graphene_matrix_t     |
+----------------------------+----------------------------+
| multiply (child transform) | translate (-pivot)         |
| translate (allocation)²    | multiply (transform)       |
| translate (pivot)²         | translate (pivot)²         |
| multiply (transform)       | translate (allocation)²    |
| translate (-pivot)         | multiply (child transform) |
+----------------------------+----------------------------+

² - likewise, these 2 translations are simplified as a
    single call to translate(allocation + pivot)

cedb5318da cogl/matrix: Relocate and update projection and transform APIs
Ideally, we would use Graphene to do that, however as of now Graphene
lacks these APIs so we still need these helpers. Since we're preparing
to get rid of CoglMatrix, move them to a separate file, and rename them
with the 'cogl_graphene' prefix.

Since I'm already touching the world with this change, I'm also renaming
cogl_matrix_transform_point() to cogl_graphene_matrix_project_point(),
as per XXX comment, to make it consistent with the transform/projection
semantics in place.
