It was for a failed expriment that tried to mmap() dmabuf memory and
find damaged regions to decrease the amount that was eventually used to
write to an onscreen, but mmap:ing is only fast enough on intel, and
it's only relevant on various server GPUs. For it to be achievable, we
need to render to system memory in a way that we don't need to copy it
out of OpenGL, but that's currently not possible.

Allow only specific files to use those deprecated APIs making
it easier to find where deprecated APIs are still in use

Group all the three config files from clutter/cogl/meta into one
and also remove unnused configurations and replace duplicated ones
This also fixes Cogl usage of HAS_X11/HAS_XLIB to match the expected
build options

- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one
Note we would still want to get rid of the _cogl_texture_init which is something
for the next commit

In future commits, we will want to create DMA-BUFs with pixel
formats other than COGL_PIXEL_FORMAT_BGRX_8888. In preparation
for that, let's start passing a new pixel format parameter to
this function, and the corresponding winsys vfunc.
All callers of this function pass COGL_PIXEL_FORMAT_BGRX_8888
for now. Next commits will change that.

This adds some plumbing to get the "default" paint flags for regular
stage painting, where one either wants to paint the overlay, or not.
If inhibited, the 'no-cursors' paint flag is used, otherwise the 'none'
flag. This will be used to allow having a per stage view hw cursor
state.

We're using clutter_stage_schedule_update() now from ClutterActor to kick
off the stage updating machinery when a redraw needs to happen.
This introduced a bunch of unnecessary calls to
clutter_stage_schedule_update() and thus
clutter_stage_view_schedule_update() when multiple actors request redraws
during the same stage update cycle, which is a very common case.
Cut off all those unnecessary calls by bailing out in
clutter_stage_schedule_update() when updates are already queued.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2679>
So far our logic for queueing redraws goes like this: Actor notices that it
needs to redraw -> actor tells stage that it needs to redraw via
clutter_stage_queue_actor_redraw() -> stage collects more and more redraws
into a QueueRedrawList before the actual stage update happens -> when
that happens, the stage collects the actual redraw clips from the actors via
clutter_actor_get_redraw_clip().
The logic behind this QueueRedrawList was that by storing a list of
redraw entries on the stage, way we can avoid traversing the whole actor
tree one more time to build the redraw clip before the stage update.
These days we have clutter_actor_finish_layout() though, which is basically
exactly that, a whole actor tree traversal that happens before every stage
update.
Since we have that now, we might as well get rid of the whole dance back and
forth between ClutterStage and ClutterActor, and simply merge the logic to
queue redraws into the finish-layout step.

Stage view users can schedule updates at ease with
clutter_stage_view_schedule_update(), but couldn't schedule update
"now". Make that easy too by adding
clutter_stage_view_schedule_update_now().

That means before-update, prepare-paint, before-paint, paint-view, after-paint,
after-update. While yet to be used, it will be used as a transient frame
book keeping object, to maintain object and state that is only valid
during a frame dispatch.

Fix a silly copy-paste mistake. Since `GObject` is the parent class,
chaining up to `dispose()` from within your `finalize()`
implementation just leads to a little memory leak and nothing worse.

When taking the scanout path we still want to clear the
redraw-clip from the stage-view in order to ensure we skip
frames in `handle_frame_clock_frame()` if no new redraw-clip
was recorded.
This was not done previously as the accumulated redraw-clip was
needed for the next repaint, likely under the assumption that
scheduling a scanout repeatedly would be computationally cost-free.
This assumption does not hold in a VRR world.
In order to archive both, an accumulated redraw-clip for the next
paint and frame-skipping during scanout, introduce new API to defer
and accumulate redraw-clips until the next repaint.

This is a signal that will be emitted between the 'before-update' and
'before-paint'. It can be used to handle things when you know whether
there is an update, and you know whether a paint or not will happen, by
looking at the current damage.

This looks like a relic of glReadPixels-based picking, the pointer
might well be outside redrawn areas, yet still require a device
update (e.g. in order to reflect the actor layout changes in the
"clear area" info).
Instead, always update all devices that are inside the view after
relayouts, the tracking on the need for that update is now done
on each ClutterStageView, instead of globally in the ClutterStage.
This theoretically fixes situations where pointers might miss
updating their "clear area" after the actor tree changed.

Make sure that when we've recreated views that we'll actually paint a
new frame for it. This was very rarely a problem, as views tend to
result in getting damage etc being queued as side effects of various
things, like layout, but e.g. when running certain tests, this might not
happen. There is no situation where we want to create a new view that
should remain unpainted, so just make sure we initialize it to become up
to date.

Updating the last_paint_volume while painting has proven itself to be
quite prone to issues: First we had to make sure actors painted by
offscreen effects get their last_paint_volumes updated correctly (see
0320649a1c50993f308344e0dd296abaad0ee6d4), and now a new issue turned up
where we don't update the paint volumes while a fullscreen unredirect is
happening.
To stop those issues from happening and to lay the foundation for using
the last_paint_volume for other things, update the last_paint_volume in
a separate step before painting instead of doing it in
clutter_actor_paint().
To save some resources, avoid introducing another traversal of the
scenegraph and add that step into the existing step of updating the
stage_views lists of actors. To properly update the paint volumes, we
need to do that after finishing the queued redraws, which is why we move
clutter_stage_maybe_finish_queue_redraws() to happen before the new
clutter_stage_finish_layout().

To make the double buffered shadow buffer damaged tiles detection
feasable, a new EGL extension is needed for creating FBO's backed by
a custom CPU memory buffer, instead of DMA buffers, as DMA buffers can
be very slow to read, much slower than just painting the shadow buffer
directly.
Leave the code there, since such an EGL extension is intended to be
added, but hide it behind an env var so that it isn't enabled by
accident.

Before each frame is maybe redrawn, push any new cursor KMS state to the
pending update. It'll then either be posted during the next page flip,
or when the same frame finishes, in case nothing was redrawn.

Just as with the frame clock, add an API to communicate that a frame did
not result in a presentation. This can't happen yet but will when we
emulate atomic cursor plane changes using legacy drmMode API.

ClutterFrame aims to carry information valid during dispatching a frame.
A frame may or may not include redrawing, but will always end with a
result.
A asynchronous page flip, for example, will result in a
CLUTTER_FRAME_RESULT_PENDING_PRESENTED, while a frame that only
dispatched events etc will result in CLUTTER_FRAME_RESULT_IDLE. Instead
of this being implicit, make the ClutterStageWindow implementation
handle this itself.

A first step towards abandoning the CoglObject type system: convert
CoglFramebuffer, CoglOffscreen and CoglOnscreen into GObjects.
CoglFramebuffer is turned into an abstract GObject, while the two others
are currently final. The "winsys" and "platform" are still sprinkled
'void *' in the the non-abstract type instances however.

In this case, since we are building the entire matrix by ourselves,
reverse the order of operations (translate + scale → scale + translate)
and build it using graphene-specific APIs.

CoglMatrix already is a typedef to graphene_matrix_t. This commit
simply drops the CoglMatrix type, and align parameters. There is
no functional change here, it's simply a find-and-replace commit.
