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.

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.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1439
Rename cogl_matrix_get_array() to cogl_matrix_to_float(), and
make it copy the floats to an out argument instead of returning
a pointer to the casted CoglMatrix struct.
The naming change is specifically made to match graphene's,
and ease the transition.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1439
Next commits, and this patchset in general, will make this patchset
obsolete, since it'll only test graphene types against each other.
If at all useful, the Euler test should be moved to graphene.

Writing tests' output to a log file makes them difficult to debug when
the test might be running on an autobuilder or CI system where only
stdout/stderr are recorded. This is particularly troublesome if a
failure is only reproducible on a particular autobuilder.
Recent Automake versions have the convention that detailed output from
failing tests is written to stdout/stderr, not just to log files, when
the VERBOSE environment variable is set; borrow that convention as a
trigger for producing detailed test output.
This was originally cogl!14, but applies equally to mutter's fork of cogl.

The property is deprecated and the current implementation simply
redirects it to ClutterActor::background-color, so remove it.
Also update the tests to set the background color directly.

If a test is not expected to succeed, then running it could be considered
to be a waste of resources, particularly if the failure might manifest
as an indefinite hang (see cogl!11), or if the test is likely to dump core
and trigger "expensive" crash-reporting mechanisms like systemd-coredump,
corekeeper, abrt or apport.
Skip the tests that are expected to fail. They can still be requested via
an environment variable, which can be set after fixing a bug to check which
tests are now passing.
Originally cogl!15, adapted for mutter's fork of cogl to use gboolean
instead of CoglBool.

When r is 128 or more, running tests compiled with the undefined behaviour
sanitizer (ubsan) reports:
test-utils.c:312:45: runtime error: left shift of 128 by 24 places cannot be represented in type 'int'
which indeed it cannot. Force the type to be unsigned 32-bit so that we
get defined behaviour.
Similarly, in test-atlas-migration, the left-shifted guint8 is promoted
to int, which again does not have enough non-sign bits available to
left-shift a value >= 128 by 24 bits. Again, force the shift to be done
in unsigned 32-bit space.
This was originally cogl!22, but applies equally to mutter's fork of cogl.

According to the cogl_bitmap_new_for_data documentation, the data is not
copied, so the application must keep the buffer alive for the lifetime
of the CoglBitmap. Freeing it too early led to a use-after-free in the
cogl unit tests. With that fixed, the test passes, so remove the known
failure annotation.
This AddressSanitizer trace is from the original cogl, but the bug and
fix apply equally to mutter's fork of cogl:

Change the warp modes test to sanity check CoglPrimitive based polygon
drawing instead of cogl_polygon(). This removes some checks, as
cogl_polygon() has explicitly documented special behaviour for automatic
wrap modes, which CoglPrimitive does not.

When painting, actors rely on semi global state tracked by the state to
get various things needed for painting, such as the current draw
framebuffer. Having state hidden in such ways can be very deceiving as
it's hard to follow changes spread out, and adding more and more state
that should be tracked during a paint gets annoying as they will not
change in isolation but one by one in their own places. To do this
better, introduce a paint context that is passed along in paint calls
that contains the necessary state needed during painting.
The paint context implements a framebuffer stack just as Cogl works,
which is currently needed for offscreen rendering used by clutter.
The same context is passed around for paint nodes, contents and effects
as well.
In this commit, the context is only introduced, but not used. It aims to
replace the Cogl framebuffer stack, and will allow actors to know what
view it is currently painted on.

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.

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;

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.

This is for all intents and purposes the same as
`cogl_object_ref/unref`, but still refers to handles rather than
objects (while we're trying to get rid of the former) so it's a bit of
unnecessary redundant API.

This was introduced in:
commit 010d16f647
Author: Robert Bragg <robert@linux.intel.com>

Adds initial GLES2 integration support
This makes it possible to integrate existing GLES2 code with
applications using Cogl as the rendering api.
That's maybe a reasonable thing for a standalone cogl to want, but our
cogl has only one consumer. So if we want additional rendering out of
our cogl layer, it makes more sense to just add that to cogl rather than
support clutter or mutter or the javascript bindings creating their own
GLES contexts.

Cogl unit tests are just functions inside normal code files that needs to be
dload'ed by the test binary.
So in case unit-tests are enabled, we need to export those symbols.
Since map file can't be overridden, use a configure_file to generate the map
file when tests are enabled, in order to export the needed symbols.
Then goes through the source files to look unit tests checking for their macro
definition and load them with the runner script.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/442
Use find-conform-unit-tests.sh to create a meson list of tests to run.
This allows to run each test as single test with meson and to remove the timeout
for all the tests.
Instead of changing 'run-tests.sh' to take test-names as arguments we can just
generate simple dummy test-files for each test, without having to change the
tooling.
