4ce4a2b134 cogl: Expose more headers for introspection
This will allow CoglFramebuffer and its implementations to be exposed
to GJS and other language bindings. This is a necessary part of the
bigger work to make framebuffer management explicit.

93e20cf21c cogl/framebuffer: Mark CoglOffscreen as a CoglFramebuffer implementation
CoglOffscreen is effectively a CoglFramebuffer, but it isn't being marked as
such by the GType machinery. This makes it impossible for introspection to
correctly set this class up.

Fix that by adding a COGL_GTYPE_IMPLEMENT_INTERFACE() code into the declaration
of CoglOffscreen. This does not have any functional changes though.

build: Make libmutter-cogl-path a dependency for test-journal
Otherwise, it might trigger the actual race condition that Continuous
is running into, and access the generated enum headers before they're
created.

build: Prefer dependencies instead of link_with
Meson uses the 'dependencies' field to determine and
parallelize build steps, but that isn't entirely true
with 'link_with'; this might cause a race condition
when generating header files while trying to build
them.

Fix that by only using 'dependencies' instead of 'link_with'.

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'.

d48d56f831 autotools: Make install directories paths more consistent
Install include files in
$prefix/include/mutter-$apiversion/[clutter,cogl,...,meta]/, and
datafiles in /usr/share/mutter-$apiversion/.... We still would conflict

installed, but it's a step in the right direction.

c6691afa38 cogl: Fix cogl_frame_info_get_frame_counter docs
The docs previously suggested that `cogl_frame_info_get_frame_counter`
returned a timestamp of an unknown clock ID. That's not correct. The
cogl source code shows that it does and must use the same clock as
`cogl_get_clock_time`.

2f260edf19 cogl: Read pixels as per the stored format
By the looks of it, commit 95e9fa10ef was taping over an Intel DRI bug
that would make it return post-swizzling pixel data on glReadPixels().
There's been reports over time of that commit resulting in wrong colors
on other drivers, and lately Mesa >17.3 started showing the same symptoms
on Intel.

But texture swizzling works by changing parameters before fragment shaders
and reading pixels from an already drawn FBO/texture doesn't involve those.
This should thus use pixel_format_to_gl_with_target(), which will result in
correctly requesting the same pixel format than the underlying texture,
while still considering it BGRA for the upper layers in the swizzling case.

d8f2f583e6 cogl-texture: refuse downloading textures in cogl_texture_get_data() on GLES
On drivers that do not support glGetTexImage2D (i.e. on GLES),
cogl_texture_get_data() has a "feature" that allows it to download
texture data by rendering the texture on an intermediate framebuffer
object and then reading back the data from there. However, this
feature requires the user to have previously set an "active"
framebuffer object in the context, which makes this very tricky
because it is not clear to the developer that he needs to do that
in order for some code to work on GLES (of course it works on
desktop GL, so nobody notices...) and additionally the code actually
crashes if an active fbo is not set!

This patch basically removes this feature in order to prevent
the crash and is in line with how this code has evolved in cogl-2.0:

483ed98777 cogl: Only do the swizzling hack for GL contexts
The GL_BGRA definition is not available for GLES2 contexts, which use
the EXT_texture_format_BGRA8888 instead, causing a build failure when
trying to use it in those contexts.

Fortunately, this hack is only relevant for GL, so let's guard it to
prevent the failure in GLES2, where that extension is used instead.

bc041e02b3 cogl: Mark vertex buffers as dynamic
Those are cached and reused across runs, which doesn't qualify to mesa
as "static" indeed. Properly marking those as dynamic is more true, and

229ac9c9dc Consider the right CONTEXT_LOST token on OpenGL ES contexts
The KHR_robustness extension defined the following token as
returned by GetError (see spec at [1]):

  CONTEXT_LOST  0x0507

As noted in the spec, this token must have a "_KHR" suffix in
an OpenGL ES context, which is not being considered here, thus
making this type of builds fail.

  GUILTY_CONTEXT_RESET_ARB    0x8253
  INNOCENT_CONTEXT_RESET_ARB  0x8254
  UNKNOWN_CONTEXT_RESET_ARB   0x8255

These tokens might not be defined in some GL implementations,
such as Mesa 13's implementation of GLES 2.0, so we need to
define them ourselves not to break those builds.

35388fb33c cogl: Use pixel_format_to_gl_with_target on bitmap uploading paths
We already do have a texture with an internal format in these paths,
so we should check the required format according to it.

This fixes CoglAtlasTexture (and CoglPangoRenderer indirectly), as
it forces a RGBA format on its texture, but pixel_format_to_gl()
anyway assumed swizzling is performed on the texture, while it is
not the case.

1705a26fc7 cogl: Prefer swizzling to convert BGRA buffers
If the GL implementation/hw supports the GL_*_texture_swizzle extension,
pretend that BGRA textures shall contain RGBA data, and let the flipping
happen when the texture will be used in the rendering pipeline.

This avoids rather expensive format conversions when forcing BGRA buffers
into RGBA textures, which happens rather often with WL_SHM_FORMAT_ARGB8888
buffers (like gtk+ uses) in little-endian machines.

In intel/mesa/wayland, the performance improvement is rather noticeable,
CPU% as seen by top decreases from 45-50% to 25-30% when running
gtk+/tests/scrolling-performance with a cairo renderer.
