6777a547ca cogl: Add 64 bit half-point pixel RGBA formats
In order to support the DRM formats DRM_FORMAT_ABGR16161616F and
friends, as well as the wl_shm formats WL_SHM_FORMAT_ABGR16161616F and
friends, cogl needs to have knowledge about said formats too.

We don't have a software implementation of the half point data types
however, so the pack/unpack methods remain unimplemented. We don't need
them for now, so it's not crucial that we add them.

For the GLES2 driver, currently only two formats are supported, and
since we don't currently have pack/unpack implementations, the other
formats will for now remain unsupported, until we have a half float
implementation.

3a474556b8 cogl-texture-2d: Flush the journal before mipmapping
In the case of indirect rendering like the first frame to use mutter's
background wallpaper:

  Texture_A -> FBO_B (Texture_B) -> FBO_C (screen)

we would be trying to render the contents of both FBO_B and FBO_C in
the same flush, before the contents of Texture_A had made it to FBO_B.
So when FBO_C wants to use mipmaps of Texture_B they didn't exist yet
and appeared all black. And the blackness would remain for subsequent
frames as cogl has now decided the mipmaps of FBO_B are no longer
"dirty" and don't need refreshing:

  FBO_B (Texture_B) (mipmaps_dirty==FALSE but black) -> FBO_C (screen)

We must flush FBO_B before referencing Texture_B for use in rendering
FBO_C. This only happens when Texture_A changes (e.g. when the user
changes their background wallpaper) so there's no ongoing performance
penalty from this flush.

c00a8e98a3 clutter/cogl: Take over global frame count responsibility

CoglOnscreen of the screen; change it into a plain counter in

2a6e8bda8d cogl/onscreen: Let swap buffer caller create frame info
We currently have mutter set a global frame counter on the frame info in
the native backend, but in order to do this from clutter, change the
frame info construction from being implicitly done so when swapping
buffers to having the caller create the frame info and passing that to
the swap buffers call.

While this commit doesn't introduce any other changes than the API, the
intention is later to have the caller be able to pass it's own state
(e.g. the global frame count) along with the frame info.

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:

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.

A texture with no pixels isn't a useful thing to have, and breaks

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

through the default color alpha, and the reason it was used there.

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

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.

Just like libmutter-clutter, and libmutter, mark exported symbols with
an COGL_EXPORT macro. This removes the .map and .map.in files previously

COGL_EXPORT macros.

unit_test_* symbols are exported by the help of the unit test defining
macro. test_* symbols are no longer supported as it proved unnecessary.

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.

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;
