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.

Workaround for <https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2538>.

37eda498f2 cogl: Don't allow creating sized textures with 0 pixels
A texture with no pixels isn't a useful thing to have, and breaks
assumptions elsewhere. For example, CoglFramebuffer assumes that after
a texture has been allocated, it will have width and height both greater
than 0.

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.

e8ea5ecd8a cogl-pango: Factor in default color alpha again
In commit d846fabda we moved to using the override color alpha, however
it was missed that the actor opacity is transferred to the PangoRenderer
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
unpremultiplied color, so we just need to change the alpha value.

Fixes effects on text actors that involve actor opacity.

ed10aea44d cogl-pango: Special case alpha of 0
pango_renderer_get_alpha() returns 0 to indicate that the alpha value
should be inherited from the environment, but we are passing it on
(and therefore making the text fully translucent).

Instead, make the text fully opaque as expected.

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.

6885c37784 cogl: Mark exported cogl symbols using COGL_EXPORT
Just like libmutter-clutter, and libmutter, mark exported symbols with
an COGL_EXPORT macro. This removes the .map and .map.in files previously
used, containing a list of semi private symbols. This symbol was out of
date, i.e. pointed to non-existing symbols, and was also replaced with
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.

77b3c0d670 cogl: Remove API implicitly switching between built in pipelines
This means cogl_set_source_color*() that switches to the opaque or
blending pipeline, or cogl_source_set_texture() which switches to the
texture pipeline.

Left is the opaque pipeline, as it is still used to compare other
pipelines to check whether they are opaque or not, and as the default
pipeline still pushed to the source stack during initialization.

9e2e44c0c2 cogl/tests/warp-modes: Test CoglPrimitive instead of cogl_polygon()
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.

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.

8e172aeecb cleanup: Use g_clear_handle_id() for g_source_remove()
It makes sure we do not forget to zero the id and lets us avoid
zero checks before. We use it for all new code, lets clean up the
existing code base.

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.
