d6f5ac5603 cogl: Remove now-unused CoglGpuInfo
This had been an entirely-too-GL-aware collection of renderer queries,
mostly to work around driver bugs and handle software drivers
intelligently. The driver workarounds have been removed (fix your
driver, and if you can't because it's closed-source, fix that first),
and we now delegate the am-i-software-or-not logic to the backend, so
this can all go

d133f94f8f cogl: Introduce and use cogl_context_is_hardware_accelerated
We delegate the answer through CoglDriverVtable::is_hardware_accelerated
since this is properly a property of the renderer, and not something the
cogl core should know about. The answer given for the nop driver is
admittedly arbitrary, yes it's infinitely fast but no there's not any
"hardware" making it so.

59a2bff8e2 cogl tests: Normally skip tests that are not expected to succeed
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.

a3cc62c285 cogl tests: Force defined behaviour for 24-bit left-shifts
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.

c3bf10d19a cogl test-premult: Don't free texture data until CoglBitmap is freed
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:

interface is implemented by MetaDrmBufferGbm. When directly scanned out,

c389aadff9 cogl: Defend against empty or unallocated framebuffers
It isn't immediately obvious that this is impossible, because there's some
"action at a distance" going on with framebuffers that have their size
set lazily, after their textures get allocated; so let's make this a
critical warning rather than crashing.

In particular, this works around a crash when gnome-shell tries to blur a
background that hasn't yet had any space allocated for it - which it seems
is really an actor layout bug, but more robustness seems good to have.

In commit d846fabda we moved to using the override color alpha, however

We actually want to factor in both alpha values, in order to respect
both foreground color alpha and actor opacity. This is done on the
unpremultiplied color, so we just need to change the alpha value.

95642d05a6 cogl/gl: Move shared functions to shared file
Cogl shares some GL functions between the GLES and the big
GL drivers. Namely, it shares _cogl_driver_gl_context_init
and _cogl_driver_gl_context_deinit between these two drivers.

The plot twist is: even though these functions are shared and
their prototypes are in cogl-util-gl-private.h, they're actually
implemented inside cogl-driver-gl.c, which is strictly only
about the big GL driver.

This is problematic when building Mutter on ARM v7, where we
need to disable OpenGL, but keep GLES enabled.

Fix this by moving the shared GL functions to a shared GL file.

72054332c5 cogl/clip-stack: Restore old matrices after drawing to stencil buffer
When using a region clip and something has a rectangle clip pushed, a
special drawing method for ClutterTexts (emit_vertex_buffer_geometry()
in cogl-pango-display-list.c) starts to fail and clipping issues with
long texts (because emit_vertex_buffer_geometry() is only used for texts
longer than 25 characters) start to appear. This specifically happened
in Looking Glass, where the StViewport of the ScrollView sets a
rectangle clips and the texts are usually longer than 25 characters.

This is caused by the changing of the perspective and modelview matrix
when drawing to the stencil buffer and started happening when
region-clipping was introduced with commit 8598b654. Even though the
changing of the matrices was done before that, too, the issue probably
didn't happen because `rect->can_be_scissor` was TRUE and no stencil
buffer clipping was used at all.

To fix this, temporarily save the old matrices, then set the new ones
and restore the old ones when we're done drawing to the stencil buffer.

This is a winsys-specific API that allows exporting a DMA buffer fd.

038a3170bf cogl/framebuffer: Add cogl_framebuffer_flush
In future patches, we'll create additional CoglFramebuffers that
will be shared via DMA-Buf with PipeWire. When recording frames,
we'll blit the current onscreen framebuffer into the shared one.

However, that presents a problem: cogl_framebuffer_blit() mimics
glBlitFramebuffer() semantics, and doesn't do an implicit flush
of the GPU command stream. As a consequence, clients may receive
unblitted or incomplete framebuffers.

We could use cogl_framebuffer_finish() to ensure the commands were
submitted to the GPU, but it is too harsh -- it blocks the CPU
completely until the commands are finished!

Add cogl_framebuffer_flush(), which ensures the command stream is
submitted to the GPU without blocking the CPU. Even though we don't
use the framebuffer specifically, it may be useful in the future
for e.g. a potential Vulkan backend to have access to the framebuffer.

49c8d42317 clutter: Introduce paint contexts
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.

92375c75f8 cleanup: Use g_clear_signal_handler() where possible
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.

d3afe4308a test: use correct enum
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;

d992722c24 cogl: correct check for COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL
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;

81bb4f0051 cogl: return correct enum type
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;

ee4638ef5c cogl/egl: Make surface current before querying buffer age
Unknown since when, we started deferring the eglMakeCurrent for the
current framebuffer till we started painting on it, which means we
are preparing for rendering a view without guarantees that the
framebuffer we will paint to is the current drawing surface for the
EGL context.

A fairly common case where that assumption will break is multimonitor
set ups, in this case we will be preparing to paint to a view while
the current draw surface is that of the previously rendered view's.

Mesa will in this case return EGL_BAD_SURFACE when querying the buffer
age, since the surface is not yet the current draw surface. This
makes us give up on buffer age checks, and paint the whole view. Since
the problem repeats when painting the next view, we are effectively
doing full-screen redraws on all monitors.

Since cogl usually works implicitly, and querying the buffer age is
meaningless if you're not meant to paint on a surface, make the surface
the current draw surface implicitly before querying the buffer age.

This brings us glorious partial invalidations back when several views
had to be repainted.

f4f7e31303 cogl: Fix GLES2 fallback
Say you're using intel gen3, you poor soul. Your big-GL maxes out at 1.5
unless you use dirty tricks, but you do have GLES2. We try to fall back
to GLES in this case, but we only ever say eglBindAPI(EGL_OPENGL_API).
So when we go to do CreateContext, even though we think we've requested
GLES 2.0, the driver will compare that "2.0" against the maximum big-GL
version, and things will fail.

Fix this by binding EGL_OPENGL_ES_API before trying a GLES context.

7c036c5896 cogl: fix a compile warning
In find_onscreen_for_xid() we want to loop over the framebuffers
and skip any that is not onscreen.

The code today does this by negating the framebuffer type variable
and skipping if that equals COGL_FRAMEBUFFER_TYPE_ONSCREEN. This
actually works as the enum used will function as a boolean:

typedef enum _CoglFramebufferType {
  COGL_FRAMEBUFFER_TYPE_ONSCREEN,
  COGL_FRAMEBUFFER_TYPE_OFFSCREEN
} CoglFramebufferType;

But it is a bit weird logic and fragile if more types are added.
(not that I can think of any different type...)

To simplify this, and to silence a warning in clang this patch just
changes it to a != test.

0556138b9f cogl/journal: Track viewport
CoglJournal tracks a few OpenGL states so that they can
be batch-applied if necessary. It also has a nice property
of allowing purely CPU-based glReadPixels() when the scene
is composed of simple rectangles.

However, the current journal implementation leaves various
other GL states out, such as dithering and the viewport.
In Clutter, that causes the journal to be flushed when
picking, touching the GPU when we didn't really need to.

Track the viewport of the framebuffer in the journal so that
we can avoid flushing the journal so often.

As the first step into removing Cogl types that are covered by

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.

6ed5d2e2b4 cogl: Remove GLX "threaded swap wait" used on Nvidia
Threaded swap wait was added for using together with the Nvidia GLX
driver due to the lack of anything equivalent to the INTEL_swap_event
GLX extension. The purpose was to avoid inhibiting the invocation of
idle callbacks when constantly rendering, as the combination of
throttling on swap-interval 1 and glxSwapBuffers() and the frame clock
source having higher priority than the default idle callback sources
meant they would never be invoked.

This was solved in gbz#779039 by introducing a thread that took care of
the vsync waiting, pushing frame completion events to the main thread
meaning the main thread could go idle while waiting to draw the next
frame instead of blocking on glxSwapBuffers().

As of https://gitlab.gnome.org/GNOME/mutter/merge_requests/363, the
main thread will instead use prediction to estimate when the next frame
should be drawn. A side effect of this is that even without
INTEL_swap_event, we would not block as much, or at all, on
glxSwapBuffers(), as at the time it is called, we have likely already
hit the vblank, or will hit it soon.

After having introduced the swap waiting thread, it was observed that
the Nvidia driver used a considerable amount of CPU waiting for the
vblank, effectively wasting CPU time. The need to call glFinish() was
also problematic as it would wait for the frame to finish, before
continuing. Due to this, remove the threaded swap wait, and rely only on
the frame clock not scheduling frames too early.

7e8a864992 cogl: Remove unused cogl-gles2 API
This was introduced in:

    Author: Robert Bragg <robert@linux.intel.com>
    Date:   Tue Mar 6 03:21:30 2012 +0000

        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.

3e68c9e8fa cogl: Replace ANGLE with GLES3 and NV framebuffer_blit
ANGLE extensions are only provided by Google's Almost Native Graphics Layer
Engine (ANGLE) implementation. Therefore they do not seem too useful for
Mutter.

The reason to drop GL_ANGLE_framebuffer_blit support is that it has more
limitations compared to the glBlitFramebuffer in GL_EXT_framebuffer_blit,
GL_NV_framebuffer_bit, OpenGL 3.0 and OpenGL ES 3.0. Most importantly, the
ANGLE version cannot flip the image while copying, which limits
_cogl_blit_framebuffer to only off-screen <-> off-screen copies. Follow-up work
will need off-screen <-> on-screen copies.

Instead of adding yet more capability flags to Cogl, dropping ANGLE support
seems appropriate.

The NV extension is added to the list of glBlitFramebuffer providers because it
provides the same support as ANGLE and more.

Likewise OpenGL ES 3.0 is added to the list of glBlitFramebuffer providers
because e.g. Mesa GLES implementation usually provides it and that makes it
widely available, again surpassing the ANGLE supported features.

Follow-up patches will lift some of the Cogl assumptions of what
glBlitFramebuffer cannot do.

cogl: Add libsysprof capture based tracing
Add the ability to add tracing instrumentation to the code. When
enabled, trace entries will generate a file with timing information
that will be processable by sysprof for generating visualization of
traces over time.

While enabled by default at compile time, it is possible to disable the
expansion of the macros completely by passing --disable-tracing to
./configure.

Tracing is so far only actually done if actually enabled on explicitly
specified threads.

This will be used by Mutter passing the write end of a pipe, where the
read end is sent to Sysprof itself via the D-Bus method 'Capture()'.

By passing that, we have to detect EPIPE that is sent when Sysprof stops
recording. Fortunately, we already ignore the signal at meta_init(), so
no need to add a custom signal handler.

Remove `-DG_DISABLE_CAST_CHECKS` from Clutter in debug builds

Add `-DG_DISABLE_CHECKS`, `-DG_DISABLE_ASSERT` and `-DG_DISABLE_CAST_CHECKS` to all
non-debug builds but `plain`, which explicitly should not have any compile flags

Use `cc.get_supported_arguments`, so it becomes more obvious to the user which flags
are set during compilation

80d11287eb cogl-path: Undeprecate framebuffer functions
It looks like deprecating the functions with explicit framebuffer/pipeline
arguments made it to (cogl) master by mistake:

https://mail.gnome.org/archives/clutter-list/2016-April/msg00008.html

We now use one of them, so this is a good time to undeprecate the lot.

7e0d185120 cogl/pipeline: Don't try to access to free'd pointer data
When free'ing a pipeline we destroy the BigState first and then the fragment and
vertex snippets lists using the big state pointer which is now invalid.
This causes a crash  when G_SLICE=always-malloc is set and using MALLOC_CHECK_.

So, invert the operations by free'ing the snippet lists first, and the big state
afterwards.

61c173b777 cogl/xlib-renderer: Save Xlib renderer data in custom winsys pointer
XLib renderer saves its data as the object cogl user data, however this data
is free'd as part of the object destruction that happens before free'ing the
renderer in _cogl_renderer_free(), from where we're calling the renderer
disconnect vfunc.
Thus in _cogl_xlib_renderer_disconnect() we happen to get an invalid pointer to
CoglXlibRenderer and we try access to it in order to close the X11 display.

This causes all the cogl tests to crash when G_SLICE=always-malloc is set and
when using MALLOC_CHECK_.

Fix this using the renderer winsys custom data instead of using cogl object data
for storing the CoglXlibRenderer, and handling the destruction of it manually.

As bonus this also makes access to the renderer data faster.

0d7a929b83 cogl: Map CoglPixelFormats to their specific properties
By providing an (internal) table to map `CoglPixelFormat`s to their
respective properties  we will be able to get rid of the unusual enum
values in the future. This is something we will need once we want to
have support for more pixel formats (such as YUV-based formats).

As an extra feature, we provide a `to_string()` method, which is quite
useful for debugging purposes (rather than deciphering enum values).

Cogl unit tests are just functions inside normal code files that needs to be

Since map file can't be overridden, use a configure_file to generate the map

20c1295a33 cogl-winsys-glx: Fix frame notification race/leak
If a second `set_{sync,complete}_pending` was queued before the idle
handler had flushed the first then one of them would be forgotten.
It would stay queued forever and never emitted as a notification.

This could happen repeatedly causing a slow leak. But worse still,
`clutter-stage-cogl` would then have `pending_swaps` permanently stuck
above zero preventing the presentation timing logic from being used.

The problem is that a boolean can only count to one, but in some cases
(triple buffering, whether intentional or accidental #334) we need it to
count to two. So just change booleans to integers and count properly.

a871d56f88 cogl: Revert swizzling for BGRA buffers
As it was originally reported on
https://bugzilla.gnome.org/show_bug.cgi?id=779234#c0, the hottest path was
convert_ubyte() in mesa. Reverting this shows no trace of those hot paths,
nor any higher than usual CPU activity.

As the improvements at the time were real, I can only conclude that pixel
conversion was happening somewhere further the pipeline, and swizzling just
helped indirectly. That got eventually fixed, so swizzling just stayed to
cause grief. And lots it caused.

Time to bin this, it seems.

Drop Autotools

On the wind I heard a sigh
As snowflakes cover fallen Makefiles
I will say this last goodbye

Meson is now coming
So ends Autotools days
Future is now coming
And we must away
Over Python and without Bashisms
Through lands where never Meson touched
By silver streams that run down to the Sea

Under parsers, beneath old legacy
Over snow one winter’s morn
I turned at last to paths that lead home
And though where the road then takes me
I cannot tell
We came all this way
But now comes the day
To bid you farewell

Many places I have been
Many sorrows I have seen
But I don’t regret
Nor will I forget
All Makefiles that took that road with me

I bid you all a very fond farewell.

d360b25b81 build: Install .pc files in correct location
If a library is provided in the positional arguments, then meson
defaults to installing the .pc file in a 'pkgconfig' subdirectory
in the library's install location. We want the files in the regular
$libdir/pkgconfig rather than $libdir/mutter-$api/pkgconfig, so
specify the location explicitly in the parameters.

clutter/clutter/meson.build:628: DEPRECATION: Library mutter-clutter-4
was passed to the "libraries" keyword argument of a previous call to

mutter-clutter-4 to "Requires" field, but this is a deprecated behaviour
that will change in a future version of Meson. Please report the issue
if this warning cannot be avoided in your case.

c681ccef3c cogl/texture-2d-gl: Bind correct target when getting data
While for normal textures, GL_TEXTURE_2D should be used, when it's an external
texture, binding it using GL_TEXTURE_2D results in an error.

Reading the specification for GL_TEXTURE_EXTERNAL_OES it is unclear whether
getting pixel data from a texture is possible, and tests show it doesn't result
in any data, but in case it would eventually start working, at least bind the
correct target for now.

b329256113 cogl/texture-2d-gl: Try to determine format for external textures
Don't just set the internal format to the dummy format "any", as that causes
code intended to be unreachable code to be reached. It's not possible to
actually know the internal format of an external texture, however, so it might
not actually correspond to the real format.

f7d4a727a8 build: Always pass --quiet to g-ir-scanner
This makes the build less verbose, as all .gir generation except for
clutters didn't pass --quiet to g-ir-scanner, making it output long
linking commands. Do this by adding a common introspection_args
variable.

While at it, put -U_GNU_SOURCE in there too, as it was always passed
everywhere as without it the scanner would log warnings.

Add Meson support for installed tests
This is the last remaining feature necessary to achieve
parity with the Autotools build.

A few changes were made to the install locations of the
tests, in order to better acomodate them in Meson:

 * Tests are now installed under a versioned folder (e.g.
   /usr/share/installed-tests/mutter-4)

 * The mutter-cogl.test file is now generated from an .in
   file, instead of a series of $(echo)s from within Makefile.

Notice that those tests need very controlled environments
to run correctly. Mutter installed tests, for example, will
failed when running under a regular session due to D-Bus
failing to acquire the ScreenCast and/or RemoteScreen names.

cogl/tests: Use tmp file to dump test results
When running installed tests, the working directory for Cogl
tests is /usr/libexec/installed-tests/mutter-cogl-4/conform,
which isn't writable by normal users.

To avoid the adding stray hidden files to the current directory,
adapt the runner script to fallback to $(mktemp) - which is
available on all platform we care about - and avoid adding
hidden files everywhere.

981b045459 cogl: Pick glReadPixels format by target, not source
Presumably glReadPixels itself can be more performant with pixel format
conversions than doing a fix-up conversion on the CPU afterwards. Hence,
pick required_format based on the destination rather than the source, so
that it has a better chance to avoid the fix-up conversion.

With CoglOnscreen objects, CoglFramebuffer::internal_format (the source
format) is also wrong. It is left to a default value and never set to
reflect the reality. In other words, read-pixels had an arbitrary
intermediate pixel format that was used in glReadPixels and then fix-up
conversion made it work for the destination.

The render buffers (GBM surface) are allocated as DRM_FORMAT_XRGB8888.
If the destination buffer is allocated as the same format, the Cogl
read-pixels first converts with glReadPixels XRGB -> ABGR because of the
above default format, and then the fix-up conversion does ABGR -> XRGB.
This case was observed with DisplayLink outputs, where the native
renderer must use the CPU copy path to fill the "secondary GPU"
framebuffers.

This patch stops using internal_format and uses the desired destination
format instead.

_cogl_framebuffer_gl_read_pixels_into_bitmap() will still use
internal_format to determine alpha premultiplication state and multiply
or un-multiply as needed. Luckily all the formats involved in the
DisplayLink use case are always _PRE and so is the default
internal_format too, so things work in practise.

Furthermore, the GL texture_swizzle extension can never apply to
glReadPixels. Not even with FBOs, as found in this discussion:
https://gitlab.gnome.org/GNOME/mutter/issues/72
Therefore the target_format argument is hardcoded to something that can
never match anything, which will prevent the swizzle from being assumed.

6502735f01 cogl: Remove mesa_46631_slow_read_pixels_workaround
This function gets hit even today on relatively modern Intel systems (I
have a Haswell Desktop with Mesa 18.2.4) if the pixel format is right.
Presumably it makes things slower for no longer a reason.

According to cb146dc515, this
functionality was refactored into a workaround path in 2012. The commit
message mentions the problem existing before Mesa 8.0.2. The number
refers to https://bugs.freedesktop.org/show_bug.cgi?id=46631 .

The use case where I hit this is when improving support for DisplayLink
video outputs. These are used through a "secondary GPU", and since
DisplayLink does not have a GPU, Mutter uses the CPU copy path with Cogl
read-pixels[1]. If the DisplayLink framebuffer was allocated as
DRM_FORMAT_XRGB8888 (the only format it currently handles correctly),
mesa_46631_slow_read_pixels_workaround would get hit. The render buffer is
the same format as the framebuffer, yet doing the copy XRGB -> XRGB ends
up being slower than XRGB -> XBGR which makes no sense.

This patch is not sufficient to fix the XRGB -> XRGB copy performance,
but it is required.

This patch reverts CoglGpuInfoDriverBug into what it was before
cb146dc515.

[1] This is not actually true until
    https://gitlab.gnome.org/GNOME/mutter/merge_requests/278 is
    merged.

4139907a7e cogl: Ensure to only clear the depth buffer if depth testing is enabled
The depth buffer is marked as invalid when 1) the framebuffer is just created,
and 2) whenever GL_DEPTH_TEST is enabled on it. This will ensure the
framebuffers attached depth buffer (if any) is properly cleared before it's
actually used, while saving needless clears while depth testing is disabled
(the default).

7d20101198 cogl-framebuffer: Remove swap_throttled config
Since now we don't set the swap throttled value based
on sync-to-vblank, we can effectively remove it from
Cogl. Throttling swap buffers in Cogl is as much a
historical artifact as sync-to-vblank. Furthermore,
it doesn't make sense to disable it on a compositor,
which is the case with the embedded Cogl.

In addition to that, the winsys vfunc for updating
whenever swap throttling changes could also be removed,
since swap throttling is always enabled now.

Removing it means less code, less branches when running,
and one less config option to deal with.

This also removes the micro-perf test, since it doesn't
make sense for the case where Cogl is embedded into the
compositor.

This commit includes following fixes for a few shell scripts:

1. Follow the best practice of quoting variables everywhere unless they
   are used in places where word-splitting and globbing can never happen.

2. Replace `command` with $(command) because the latter is easier to use
   and read.

3. Don't use "$@" in places expecting a string because it is an array
   of strings instead of a single string.

ef85d1a643 Add meson build support
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.

There are some differences between the autotools setup and the new
meson. Here are a few:

The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.

The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.

Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
