When commit 91c6a144da synced shadows with Adwaita, it removed the
shadow completely from attached modal dialogs. However Adwaita uses
the same shadow for all dialogs (modal or not), so do the same here.

We need to use pixel size of the monitor in order to generate a valid
texture with full quality for current monitor
In spanned case the background should cover all the differently scaled monitors
thus we scale the texture up to the maximum scaling level and then we resample
it drawing only each side in the monitor it should occupy using the proper
scaling level.
In wallpaper mode (or color mode) for example we don't need to scale the area,
also the texture size we return should be unscaled, not to confuse
MetaBackgroundActor making it use more space than needed.

To be used to translate absolute cursor positions to relative positions,
as well as to determine whether a cursor sprite is inside the stream or
not. It also helps calculating the scale the cursor sprite needs to be
scaled with to be in stream coordinate space.

There are most likely no GNOME users left still using hardware that
does not support NPOT textures. Further more, they would crash much
earlier and never hit this code-path. So remove the unnecessary check
here.

This implements the viewporter protocol which offers a cropping and scaling
capabilities to wayland clients.
There are several use cases for this, for example video players and games,
both as a convenience function and as potential performance optimization when
paired with hardware overlays etc.

Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

Previously, the clipping rectangle passed to
`meta_surface_actor_get_image()` was updated with the actual texture
size, but recent changes in `meta_shaped_texture_get_image()` now keep
the caller's clipping rectangle unchanged.
The implementation of `meta_window_actor_capture_into()` was relying on
the old behavior of updating the passed clipping rectangle, but now that
it's kept unchanged, the actual clipping rectangle used to copy the data
is wrong, which causes either a distorded image or worse, a crash of
mutter.
Use the resulting cairo image size to copy the data instead of the
clipping rectangle to avoid the issue and get the expected size.

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.
The texture tower can return no texture e.g. if the calculated level is
negative. This was handled before, but regressed with
e1370ee209. This fixes a potential crash
observed occasionally when starting Firefox nightly using the Wayland
backend in overview mode.
Now that everything is settled, from the initialization
process to the subclasses to moving code to the compositor,
MetaWindowActor can be a proper abstract class that cannot
be instantiated.
Thus, make MetaWindowActor an abstract class.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
This vfunc was added as a was to work around the convoluted
initialization process. Now that we figured it out and moved
the MetaWindowActor-specific initialization to constructed(),
we can override that.
Remove post_init() and use GObject.constructed() entirely.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
MetaWindowActor breaks layering isolation by accessing
and injecting itself into compositor->windows. This is
a bad practice, and effecticely makes returning the
new actor useless, since we doesn't even use the return
value.
Move window actor creation to under MetaCompositor and
stop violating (too badly) the resposabilities of each
component. This moves meta_window_actor_new() into
meta_compositor_add_window().
Also, move the remaining initialization code to the
GObject.constructed vfunc.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
Document the roles of MetaSurfaceActor and MetaWindowActor,
and when their subclasses are used.
(And this is actually the first real documentation under
src/compositor/README!)
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
MetaWindowActor handles sending _NET_WM_FRAME_* X atoms to
clients - even pure Wayland clients.
Now that we have Wayland- and X11-specific implementations of
MetaWindowActor, we can delegate this to MetaWindowActorX11,
and allow pure Wayland apps to not even connect to
MetaSurfaceActor:repaint-scheduled.
Do that by moving all the X11-specific code to the X11-specific
MetaWindowActorX11 class. Add vfuncs to MetaWindowActorClass
that are necessary for the move, namely:
* pre_paint() and post_paint()
* post_init()
* frame_complete()
* set_surface_actor()
* queue_frame_drawn()
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
Those are stub specialized classes for MetaWindowActor. This will
help ensuring that we do not execute X11-specific code paths on
pure Wayland clients.
The relationship between the window actor and the surface is the
following:
* Wayland: MetaWindowActorWayland + MetaSurfaceActorWayland
* X11: MetaWindowActorX11 + MetaSurfaceActorX11
* Xwayland: MetaWindowActorX11 + MetaSurfaceActorWayland
It is not possible to have MetaWindowActorWayland backed by a
MetaSurfaceActorX11 surface.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
We will introduce specialized MetaWindowActors for X11
and Wayland in the future, so it needs to be derivable.
Make it a derivable class, and introduce a private field.
The MetaWindowActorClass definition is in the private
header in order to prevent external consumers of Mutter
to create MetaWindowActor implementations of their own.
That is, MetaWindowActor is only internally derivable.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/368
EGLStream textures are imported as GL_TEXTURE_EXTERNAL_OES and reading
pixels directly from them is not supported. To make it possible to get
pixels, create an offscreen framebuffer and paint the actor to it, then
read pixels from the framebuffer instead of the texture directly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/362
When a texture is transformed in any way (e.g. Wayland buffer
transforms), we cannot just fetch the pixels from the texture directly
and be done with it, as that will result in getting the untransformed
pixels.
To properly get the pixels in their right form, first draw to an
offscreen framebuffer, using the same method as when painting on the
stage, then read from the framebuffer into a cairo image surface.

Implements the `MetaScreenCastWindow` interface for screen-cast
`RecordWindow` mode.
`meta_window_actor_capture_into()` implementation is still pretty crude
and doesn't take into account subsurfaces and O-R windows so menus,
popups and other tooltips won't show in the capture.
This is left as a future improvement for now.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/306
The shader used for computing a vignette currently has two
problems:
* The math is wrong such that the vignette isn't stretched
across the whole actor and so ends abruptly
* There is noticeable banding in its gradient
This commit corrects both problems by fixing the computing
and introducing noise dithering.
This adds the necessary bits to support Wayland buffer transforms.
The main part here is to properly setup the Cogl pipeline
and to recalculate the size of the painted area accordingly,
so culling etc. still works.
The choosen approach additionally lays groundwork for Wayland
wp_viewporter support.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/322
It cuts out some of the GObject boilerplate, and gives us g_autoptr()
support for free.
Since this changes the ABI, we also need to bump the libmutter API
version.
Following up last commit, this commit adds a CoglFramebuffer
argument to meta_shadow_paint(), and stops using the draw
framebuffer internally.
The only consumer of this API, MetaWindowActor, still passes
the draw framebuffer though.
MetaShadow.paint() uses Cogl implicit APIs (cogl_rectangle* ones, in
this case) to paint shadows with the shadow pipeline.
Replace those calls by cogl_framebuffer_draw_textured_rectangle()
calls, that achieve the exact same result but with the non-deprecated
API.
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'.
