Most of the layer computation that the stack does actually depends
on the windowing backend, so we will move it to a vfunc.
However before we do that, split out the bit that will be shared.

When a window that should be stacked above another one is placed in a lower
layer than the other window, we currently allow promoting it to the higher
layer when it has a "transient type". We should do the same when the window
is an actual transient of the other window.
This is particularly relevant for wayland windows, where types play a
much smaller role: Transient windows like non-modal dialogs (and since
commit 666bef7a, popup windows as well) currently end up underneath their
always-on-top parent.

This was wrongly introduced in 75cffd0ec4. As the comment above explains, we
only want to queue redraws in response to surface/buffer damage.
This triggered a full redraw when using DMA buffers on Wayland as we currently
create a new texture on every buffer_attach(), breaking partial invalidation.

There might be some inconsistent event for which we don't have a known
source device.
In the current state we don't handle them and we could crash when getting
the current device tool.
So, add an utility function that retrieves the source device for an event
that warns if no device is found, and use this for Motion, Key and Button
events.
In case we don't have a valid source in such case, just return early instead
of trying to generate invalid clutter events.

Add an assert that we don't have a MetaWindow::monitor pointer that
points to an old MetaLogicalMonitor. After this, and the other
monitors-changed callbacks have been called, the old MetaLogicalMonitor
will be destoryed, thus if we didn't update the pointer here, we'll
point to freed memory, and will eventually crash later on.

We do check the clip area as an optimization to know which input devices
might need updating state after a relayout (Assuming that if a device is
under a non-painted area, it's actor beneath didn't change).
Use the clip region for this, and drop the last usage of the clip region
bounds.

This commit was split out from `cleanup: Use g_clear_signal_handler()
where possible` as it fixes an actual signal leak and should therefore
get backported to stable releases.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/940
This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

On wl_data_source destruction we used to indirectly unset the DnD selection
owner via the wl_resource destructor triggering the destruction of the
MetaWaylandDataSource, which would be caught through the weak ref set by
the MetaWaylandDragGrab.
This works as long as the grab is held, however we have a window between
the button being released and the drop site replying with
wl_data_offer.finish that the MetaWaylandDataSource is alive, but its
destruction wouldn't result in the call chain above to unsetting the DnD
source.
In other selection sources, we let the MetaWaylandDataDevice hold the
"ownership" of the MetaWaylandDataSource, and its weak ref functions unset
the respective MetaSelection owners. Do the same here, so the
MetaWaylandDataSource destruction is listened for all its lifetime.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
This is wrong for both clipboard and DnD, as the selection source
will still be able to focus another surface, and churn another
wl_offer.
We should just detach the data offer from the data source in this
case, and let the source live on. However, we should still check
that there is a source and an offer to finish DnD, do that when
handling the drop operation instead.
https://gitlab.gnome.org/GNOME/mutter/issues/591
Those were used to signal clipboard ownership around, but that got
replaced by MetaSelection and friends. These signals are no longer
listened on, so can be safely removed.

The function create_texture() in test-wrap-modes.c takes a
TestUtilsTextureFlags. However a CoglTextureFlags is passed instead
in two calls. As the enums are identical this patch changes it to
use the TestUtils type.
The enum definitions:
typedef enum
{
COGL_TEXTURE_NONE = 0,
COGL_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
COGL_TEXTURE_NO_SLICING = 1 << 1,
COGL_TEXTURE_NO_ATLAS = 1 << 2
} CoglTextureFlags;
typedef enum
{
TEST_UTILS_TEXTURE_NONE = 0,
TEST_UTILS_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
TEST_UTILS_TEXTURE_NO_SLICING = 1 << 1,
TEST_UTILS_TEXTURE_NO_ATLAS = 1 << 2
} TestUtilsTextureFlags;

In _cogl_offscreen_gl_allocate we only want to perform certain actions if
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL is not set in create_flags.
We perfrom this check with:
if (!offscreen->create_flags & COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL)
which is not correct as we negate the create_flags before the bitwise &.
It happens to work as intended though, as CoglOffscreenFlags only has one
element, and that element has the value 1. If the flag is not set then the
nagation of create_flags is true and the bitwise and with the element value
is true as well.
If any flag is set then the negation will give 0 and the bitwise & will be
false.
So while it works correctly it is fragile as either additional flags or a
change in the enum element value will break this check. This patch makes
things a bit more safe by adding parentheses to let the bitwise & happen
before the negation.
Definition of the enum:
typedef enum
{
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL = 1
} CoglOffscreenFlags;

cogl_pipeline_get_front_face_winding() is supposed to return a CoglWinding. It
takes a CoglPipeline as argument and does the following input validation:
g_return_val_if_fail (cogl_is_pipeline (pipeline),
COGL_PIPELINE_CULL_FACE_MODE_NONE);
The returned COGL_PIPELINE_CULL_FACE_MODE_NONE is not a winding.
The function was added with this check 8 years ago in
5369b3c601
I do not see any of the two options in the CoglWinding as particularly good
choice for a return value on bad input, but let's go with
COGL_WINDING_CLOCKWISE as that is equivalent with the behavior for all
these years.
Definitions of the two enums:
typedef enum
{
COGL_WINDING_CLOCKWISE,
COGL_WINDING_COUNTER_CLOCKWISE
} CoglWinding;
typedef enum
{
COGL_PIPELINE_CULL_FACE_MODE_NONE,
COGL_PIPELINE_CULL_FACE_MODE_FRONT,
COGL_PIPELINE_CULL_FACE_MODE_BACK,
COGL_PIPELINE_CULL_FACE_MODE_BOTH
} CoglPipelineCullFaceMode;

CallyTexture is an accessibility object associated with ClutterTexture.
ClutterTexture is going away, so prepare by first removing the
accessibility object that would be constructed for it.
