a94841abf1 cogl: Remove color write masks from the framebuffer and pipeline API
The only thing using this is its own tests, and it's difficult to

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.

a81435ab5f cogl: Remove CoglBool, use gboolean instead
This basically reverts commit 54735dec, which tried to avoid the
GLib-defined types in favor the standard C ones. One exception to this
is the bool type, for which the commit introduces a new type CoglBool.

Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of `int`) are completely compatible with bool (size `char`).

programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.

don't expose such packages to pkg-config, but only use them at build time.

Drop Autotools
I saw Meson fade from the sky
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.

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.

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.

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

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.

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'.

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:

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,

4ebc55f2b3 Make libmutter and friends parallel installable
In order to minimize the amount of breakage, while at the same time
making it easier to make backward incompatible changes needed to
continue turning libmutter into a capable Wayland compositor, make the
libmutter and friends (libmutter-clutter, libmutter-cogl*) parallel
installable by adding a version number to the name. This changes
various filenames, for example what previously was libmutter.so is now
libmutter-0.so (assuming the version for now is 0), and
libmutter-clutter-1.0.so is now libmutter-clutter-0.so. The pkg-config
filenames and GObject introspection has been renamed to reflect this as
well.

This enables a downstream compositor rely on a specific version of the
libmutter API, while gracefully handling API/ABI changes by having to
update to the new version at their own pace.

Mutter (and libmutter users) are the only users of this version of
cogl, and will more or less only use the cogl-1.0, cogl-2.0 and cogl
experimental API variants, and having the possibility of having
different API versions of the same API depending on what file includes
it is error prone and confusing. Lets just remove the possibility of
having different versions of the same API.

28a898a22f Use signals instead of onscreen framebuffer frame callbacks
CoglFrameInfo is a frame info container associated with a single
onscreen framebuffer. The clutter stage will eventually support drawing
a stage frame with multiple onscreen framebuffers, thus needs its own
frame info container.

This patch introduces a new stage signal 'presented' and a accompaning
ClutterFrameInfo and adapts the stage windows and past onscreen frame
callbacks users to use the signal and new info container.

1c1ad69f26 winsys-egl-kms: dont create 0x0 surface
commit 188752158 changed cogl to stop needlessly creating its own
monitor output configuration when mutter would just soon overwrite
it anyway.

Unfortunately, that commit is causing a crash in some cases because
cogl will now create and later draw to a 0x0 egl surface until mutter
sets the monitor layout.

This commit changes cogl to avoid creating and using a surface, before
it knows how big of a surface to create.

4cb750928e winsys: wayland: destroy eglsurface when destroying associated native window
On Wayland deinit() of an onscreen buffer is going to destroy the
associated native window of an EGLSurface. So we should destroy the
EGLSurface as well otherwise we might end up confusing the GL driver.

We also currently guard against setting a EGL_NO_SURFACE as current
EGLSurface, but this shouldn't be a problem if we have a surfaceless
context. So we allow surface destruction under that condition.

If cogl fails to open the drm device, initialize gbm, or open the

200c4032ac kms-winsys: Defer setting new surfaces until swap buffers
We can't just destroy and replace the EGL and gbm surfaces while
they are still in use i.e. while there is a pending flip. In fact, in
that case, we were calling gbm_surface_destroy() on a surface that
still had the front buffer locked and then, on the flip handler,
gbm_surface_release_buffer() for a buffer that didn't belong to the
new surface.

Instead, we still allocate new surfaces when requested but they only
replace the old ones on the next swap buffers when we're sure that the
previous flip has been handled and buffers properly released.

5ccd2825c7 glx: Precisely wait for the next vblank
Currently the code queries the current msc then tries to approximate the
value of the next msc satisfing the modulus 2 for when to wait. This
introduces some instability as the msc may tick over during the
roundtrip leading to a 32ms wait instead of a 16ms wait. This happens
often enough to cause jerky animations, and affect gnome-shell-perf-tool.

A simpler solution is just use a single roundtrip by using WaitForMsc to
ask the driver to compute the next vblank itself.

52a646abc5 Use the EGL_KHR_surfacless_context extension
The surfaceless context extension can be used to bind a context
without a surface. We can use this to avoid creating a dummy surface
when the CoglContext is first created. Otherwise we have to have the
dummy surface so that we can bind it before the first onscreen is
created.

The main awkward part of this patch is that theoretically according to
the GL and GLES spec if you first bind a context without a surface
then the default state for glDrawBuffers is GL_NONE instead of
GL_BACK. In practice Mesa doesn't seem to do this but we need to be
robust against a GL implementation that does. Therefore we track when
the CoglContext is first used with a CoglOnscreen and force the
glDrawBuffers state to be GL_BACK.

There is a further awkward part in that GLES2 doesn't actually have a
glDrawBuffers state but GLES3 does. GLES3 also defaults to GL_NONE in
this case so if GLES3 is available then we have to be sure to set the
state to GL_BACK. As far as I can tell that actually makes GLES3
incompatible with GLES2 because in theory if the application is not
aware of GLES3 then it should be able to assume the draw buffer is
always GL_BACK.

a0441778ad This re-licenses Cogl 1.18 under the MIT license
Since the Cogl 1.18 branch is actively maintained in parallel with the
master branch; this is a counter part to commit 1b83ef938fc16b which
re-licensed the master branch to use the MIT license.

This re-licensing is a follow up to the proposal that was sent to the
Cogl mailing list:
http://lists.freedesktop.org/archives/cogl/2013-December/001465.html

Note: there was a copyright assignment policy in place for Clutter (and
therefore Cogl which was part of Clutter at the time) until the 11th of
June 2010 and so we only checked the details after that point (commit
0bbf50f905)

For each file, authors were identified via this Git command:
$ git blame -p -C -C -C20 -M -M10  0bbf50f905..HEAD

We received blanket approvals for re-licensing all Red Hat and Collabora
contributions which reduced how many people needed to be contacted
individually:
- http://lists.freedesktop.org/archives/cogl/2013-December/001470.html
- http://lists.freedesktop.org/archives/cogl/2014-January/001536.html

Individual approval requests were sent to all the other identified authors
who all confirmed the re-license on the Cogl mailinglist:
http://lists.freedesktop.org/archives/cogl/2014-January

As well as updating the copyright header in all sources files, the
COPYING file has been updated to reflect the license change and also
document the other licenses used in Cogl such as the SGI Free Software
License B, version 2.0 and the 3-clause BSD license.

This patch was not simply cherry-picked from master; but the same
methodology was used to check the source files.

dd7b1d53db Allocate immediately in _cogl_egl_texture_2d_new_from_image
The _cogl_egl_texture_2d_new_from_image function has a CoglError
argument which implies that it is unlike the other texture
constructors and returns errors immediately rather than having a
delayed-allocation mechanism. cogl_wayland_texture_2d_new_from_buffer
which calls it is also like this. We can't rely on delayed-allocation
semantics for this without changing the applications because the
texture needs to be allocated before the corresponding EGLImage is
destroyed. This patch just makes it immediately allocate.

A better patch might be to remove the error argument to make it
obvious that there are delayed-allocation semantics and then fix all
of the applications.

This was breaking Cogland and Mutter.

7bf0fe9df8 Don't dereference an unitialised pointer in _cogl_container_of
The previous implementation was dereferencing the sample pointer in
order to get the offset to subtract from the member pointer. The
resulting value is then only used to get a pointer to the member in
order to calculate the offset so it doesn't actually read from the
memory location and shouldn't cause any problems. However this is
probably technically invalid and could have undefined behaviour. It
looks like clang takes advantage of this undefined behaviour and
doesn't actually offset the pointer. It also generates a warning when
it does this.

This patch splits the _cogl_container_of macro into two
implementations. Previously the macro was always used in the list
iterator macros like this:

SomeType *sample = _cogl_container_of(list_node, sample, link)

Instead of doing that there is now a new macro called
_cogl_list_set_iterator which explicitly assigns to the sample pointer
with an initial value before assigning to it again with the real
offset. This redundant initialisation gets optimised out by compiler.

The second macro is still called _cogl_container_of but instead of
taking a sample pointer it just directly takes the type name. That way
it can use the standard offsetof macro.

This adds COGL_PIXEL_FORMAT_RG_88 and COGL_TEXTURE_COMPONENTS_RG in

This is only available on GL 3, GL 2 with the GL_ARB_texture_rg

format is always supported for images because Cogl can easily do the
conversion if an application uses this format to upload to a texture
with a different format.

If an application tries to create an RG texture when the feature isn't
supported then it will raise an error when the texture is allocated.

5085919acc pipeline-cache: Prune old unused pipelines when the cache gets too big
Previously when a pipeline is added to the cache it would never be
removed. If the application is generating a lot of unique pipelines
this can end up effectively leaking a large number of resources
including the GL program objects. Arguably this isn't really a problem
because if the application is generating that many unique pipelines
then it is doing something wrong anyway. It also implies that it will
be recompiling shaders very often so the cache leaking will likely be
the least of the problems.

This patch makes it keep track of which pipelines in the cache are in
use. The cache now returns a struct representing the entry instead of
directly returning the pipeline. This entry contains a usage counter
which the pipeline backends can use to mark when there is a pipeline
alive that is using the cache entry. When the hash table decides that
it's a good time to prune some entries, it will make a list of all of
the pipelines that are not in use and then remove the least recently
used half of the pipelines. That way it is less likely to remove
pipelines that the application is actually regenerating often even if
they aren't in use all of the time.

When the cache is pruned the hash table makes a note of how small the
cache could be if it removed all of the unused pipelines. The hash
table starts pruning when there are more entries than twice this
minimum expected size. The idea is that if that case it hit then the
hash table is more than half full of useless pipelines so the
application is generating lots of redundant pipelines and it is a good
time to remove them.

af7398788a remove internal_format and redundant error arguments
Texture allocation is now consistently handled lazily such that the
internal format can now be controlled using
cogl_texture_set_components() and cogl_texture_set_premultiplied()
before allocating the texture with cogl_texture_allocate(). This means
that the internal_format arguments to texture constructors are now
redundant and since most of the texture constructors now can't ever fail
the error arguments are also redundant. This now means we no longer
use CoglPixelFormat in the public api for describing the internal format
of textures which had been bad solution originally due to how specific
CoglPixelFormat is which is missleading when we don't support such
explicit control over the internal format.

cbd6951134 introduce texture loaders to make allocations lazy
This introduces the internal idea of texture loaders that track the
state for loading and allocating a texture. This defers a lot more work
until the texture is allocated.

There are several intentions to this change:

- provides a means for extending how textures are allocated without
  requiring all the parameters to be supplied in a single _texture_new()
  function call.

- allow us to remove the internal_format argument from all
  _texture_new() apis since using CoglPixelFormat is bad way of
  expressing the internal format constraints because it is too specific.

  For now the internal_format arguments haven't actually been removed
  but this patch does introduce replacement apis for controlling the
  internal format:

    cogl_texture_set_components() lets you specify what components your
    texture needs when it is allocated.
    cogl_texture_set_premultiplied() lets you specify whether a texture
    data should be interpreted as premultiplied or not.

- Enable us to support asynchronous texture loading + allocation in the
  future.

Of note, the _new_from_data() texture constructors all continue to
allocate textures immediately so that existing code doesn't need to be
adapted to manage the lifetime of the data being uploaded.

that followed. The gtk-doc comments for cogl_texture_set_premultiplied()

08ba5c64b9 framebuffer: if size unknown; allocate for size/vp queries
This ensures framebuffers are implicitly allocated when querying the
width, height or viewport width/height if the framebuffer's size is
currently unknown. The plan is to allow texture backends to defer
calculating the size of textures until they are allocated which in turn
means we won't know the size of offscreen framebuffers until the texture
has been allocated. Potentially we could be more specific about this in
the future and only ensure the texture is allocated, but for now it will
be simplest to just ensure the framebuffer is allocated.

Note: in the case of onscreen buffers which are always initialized with
a requested size we are careful to avoid triggering an allocation when
this is queried otherwise we will see recursion when the winsys code
queries the requested size during allocation.

24412798dc Revert "Revert "Remove the framebuffer's stack of clip stacks""
This reverts commit bc41489336.

The reason this was causing problems for Clutter is that it defines
COGL_ENABLE_EXPERIMENTAL_2_0_API which is meant to cause the Cogl
headers not to declare the deprecated API. The reverted patch moved
some additional clipping API to a deprecated header which was
previously being used by Clutter. Clutter was still successfully
compiling but with some warnings for the missing function
declarations. However when the binary is run the clipping would get
completely messed up because it would assume all of the arguments to
the functions are integers instead of floats and the wrong values
would be passed.

Clutter now has commit to make it use the 2.0 API instead of the
deprecated functions so the revert is no longer necessary.

There used to be a function called cogl_clip_stack_save in the public

to save the clip state. This is no longer necessary because each

in master. However the code to maintain the stack of stacks was
retained. This patch removes it in an effort to simplify the code.

On the 1.18 branch this function is deprecated and the documentation

c5644723f8 Use COGL_FLAGS_* for the context's private feature flags
Previously the private feature flags were stored in an enum and we

add -2³¹ as one of the values which might cause problems. To avoid
this we'll just use an fixed-size array of longs and use indices for
the enum values like we do for the public features.

A slight complication with this is in the CoglDriverDescription where
we were previously using a static intialised value to describe the set
of features that the driver supports. We can't easily do this with the
flags array so instead the features are stored in a fixed-size array
of indices.

6436cd073d Declare interface types as void and remove cast macros
This declares the interface types CoglFramebuffer, CoglBuffer,
CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when
including the public cogl.h header so that users don't have to use lots
of C type casts between instance types and interface types.

This also removes all of the COGL_XYZ() type cast macros since they do
nothing more than compile time type casting but it's less readable if
you haven't seen that coding pattern before.

Unlike with gobject based apis that use per-type macros for casting and
performing runtime type checking we instead prefer to do our runtime
type checking internally within the front-end public apis when objects
are passed into Cogl. This greatly reduces the verbosity for users of
the api and may help reduce the chance of excessive runtime type
checking that can sometimes be a problem.

without review and without first going into the master branch I think
it makes sense to just revert it and apply a new version to master.

This reverts commit 3eb63f67a3.

5c5715f4da framebuffer: Fix clip tracking in the unclipped case
Leaving the clip bounds untouched means that it will retain the stale value
of whatever it was when we last had a clip; reset it so that it contains the
full framebuffer contents instead.

a8e04a7d6b Add API to control per-framebuffer depth writing
Add framebuffer methods cogl_framebuffer_[gs]et_depth_write_enabled()
and backend bits to pass the state on to glDepthMask().

This allows us to enable or disable depth writing per-framebuffer, which
if disabled saves us some work in glClear(). When rendering, the flag
is combined with the pipeline's depth writing flag using a logical AND.

Depth writing is enabled by default.

18486a6aa9 egl: forward declare wl_resource for compatibility
Depending on what version of Mesa you have then eglQueryWaylandBuffer
may take a wl_buffer or wl_resource argument and the EGL header will
only forward declare the corresponding type.

The use of wl_buffer has been deprecated and so internally we assume
that eglQueryWaylandBuffer takes a wl_resource but for compatibility we
forward declare wl_resource in case we are building with EGL headers
that still use wl_buffer.

c1724eff60 framebuffer: NOP _set_color_mask if mask isn't changing
This makes cogl_framebuffer_set_color_mask immediately bail out if the
given mask equals the framebuffer's current mask, since the cost of
flushing the journal and flushing the gl state will hugely outweigh the
cost of the check.

This updates the definition of _COGL_STATIC_ASSERT to just use
_Static_assert if available or be NOP if not. We no longer worry about
supporting static assertions with older compilers. This fixes some
verbose warnings that newer compilers were giving with the old typedef
based static assertion method.

669b3ad864 pipeline: notify all progends of changes
When a pipeline is notified of a change we now make sure to notify all
progends of that change not just the progend directly associated with
that pipeline. A pipeline can have private state associated with it from
multiple progends because descendants will always try and cache state on
ancestors to maximize the chance that the state can later be re-used.
Descendants may be using different progends than the ancestors that they
cache state with.

a93e789a7c Avoid conflicting client/server wayland includes
This avoids including wayland-server.h in cogl-display-private.h which
avoid lots of compile time warnings that wl_buffer is deprecated. The
problem is that wl_buffer is also exposed in the client side headers and
isn't deprecated for clients. If we end up including the client and
server headers in the same compilation unit we can get conflicting
definitions.

fa855b7c45 Start clearly separating deprecated code
This makes a start on clearly factoring the deprecated code of core Cogl
into a deprecated/ directory. Ideally we want to get to the point where
all code here can be re-worked in terms of the public 2.0 api so that it
can be kept indefinitely for cogl 1.x api compatibility without
cluttering the core code base itself. If we can do this then we can
avoid maintaining the Cogl 1.x branches in parallel with master which
would reduce the maintenance effort.
