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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/932
ClutterTexture is going to be removed, so remove interactive tests that
stand in the way for that. Some test texture features, while some makes
heavy use of ClutterTexture to implement their testing. Remove these
tests to prepare for the removal of ClutterTexture.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/932
ClutterTexture is deprecated, lets remove the trivial usage with a
simple gdk-pixbuf using constructor putting pixel contents into a
ClutterImage then putting said image in a plain ClutterActor.
Tested partially, as the interactive tests cannot be properly run at the
moment.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/932
As was with the tests run via meson test, for the interactive tests we
too need to configure the mutter backend and initialize things in order
to be able to run any tests.

Properly take the panel_orientation_transform into account in
update_monitor_crtc_cursor. This fixes us sometimes drawing the cursor
on two monitors at the same time as we did not properly swap the crtc
width/height when a panel_orientation_transform is active.

clutter_event_get_scroll_finish_flags() should return a ClutterScrollFinishFlags
but due to what looks like a bad copy/paste it instead returns a
ClutterScrollSource on asserts.
The definitions of the enums are these:
typedef enum
{
CLUTTER_SCROLL_SOURCE_UNKNOWN,
CLUTTER_SCROLL_SOURCE_WHEEL,
CLUTTER_SCROLL_SOURCE_FINGER,
CLUTTER_SCROLL_SOURCE_CONTINUOUS
} ClutterScrollSource;
typedef enum
{
CLUTTER_SCROLL_FINISHED_NONE = 0,
CLUTTER_SCROLL_FINISHED_HORIZONTAL = 1 << 0,
CLUTTER_SCROLL_FINISHED_VERTICAL = 1 << 1
} ClutterScrollFinishFlags;
The asserts would only return CLUTTER_SCROLL_SOURCE_UNKNOWN. This
is equal to CLUTTER_SCROLL_FINISHED_NONE which this patch uses
instead. Thus no functional change is intended. This only fixes a
compile warning.

Clutter has a draw debug mode that allows for painting
paint volumes. Right now, this debug mode uses the old
immediate paint mode.
Switch the painting of paint volumes to use paint nodes,
and sneak a few minor style cleanups.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/890
Now that we unconditionally use ClutterActorNode to
paint ClutterActors, move the PAINT private flag to
the ClutterActorNode. This way, we can run the paint
on the actor anywhere inside the paint tree.

It seems that sometimes these functions are called by Javascript in
GNOME Shell during tear down. This causes segfaults and crash reports,
but without any backtraces other than the entry and exit points into
gjs.
In order to get more useful information about where these calls come
from, validate the input passed gracefully, by complaining in the log
and returning NULL values.
