The way code was structured made it easy to misunderstand things as the
surface actor of a window actor could change over time. So is not the
case, however, the intention of the corresponding "update" function was
so that a surface actor could be assigned to a window actor as soon as
the X11 window was associated with its corresponding wl_surface, if the
window in question came from Xwayland.
Restructure the code and internal API a bit to make it clear that a
window actor only once gets a surface actor assigned to it, and that it
after that point never changes.

In MetaWindowActor creation we're setting the compositor private (i.e. the
window actor itself) of a window before creating the surface actor, and so
passing to the it a window without its compositor side set.
Since the surface actor might use the parent actor, set this before updating
the surface.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/660
As per commit 80e3c1d set_surface_actor has been added, meant to do different
things depending on the backend, like connecting to signals under X11.
However, the vfunc isn't ever used, making the X11 surfaces not to react to
repaint-scheduled signal.

window-actor: Turn into a derivable class
made the previous instance struct a instance private struct, but didn't
remove the parent field. Since it's unused, there is no point in keeping
it around, so lets drop it.

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.

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.

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
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
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
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.

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.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
They are X11 specific functions, used for X11 code. They have been
improved per jadahl's suggestion to use gdk_x11_lookup_xdisplay and
gdk_x11_display_error_trap_* functions, instead of current code.

- Moved xdisplay, name and various atoms from MetaDisplay
- Moved xroot, screen_name, default_depth and default_xvisual
from MetaScreen
- Moved some X11 specific functions from screen.c and display.c
to meta-x11-display.c

When using plugins, the effects will affect the MetaWindowActor size
and position.
Add a new signal "effects-completed" wired to the corresponding
MetaWindowActor which is emitted when all effects are completed so that
derived objects can be notified when all effects are completed and use
the actual size and position.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/104
It looks that there are some extensions that run a Mainloop on startup,
causing to dispatch a clutter paint before the compositor is even available.
In such scenario a MetaWindow could try to start a simple effect
using a compositor plugin which is not there yet.
Then in order to catch these bugs we can now assert that the expected
conditions are valid, so that gnome-shell will provide a dumpstack to
debug the real offending JS code.
https://bugzilla.gnome.org/show_bug.cgi?id=789223
There are cases when no compositor is available (yet) but a MetaWindow tries
to start a simple effect using a compositor plugin which is not available.
In that case we should just ignore any request and protect ourselves from
crashes.

Turn MetaOutput into a GObject and move it to a separate file. This
changes the storage format, resulting in changing the API for accessing
MetaOutputs from using an array, to using a GList.

We currently don't have any shadow class for combo box popups,
which means the default shadow of normal windows is used. That's
clearly odd given that the two are very different, and isn't
consistent with GTK+-3's client-side shadows for popups. While
we could add a dedicated shadow class, the designers are fine
with reusing the existing shadow for dropdown-menus, so let's
do that.
https://bugzilla.gnome.org/show_bug.cgi?id=744667
If the meta_window_actor_effect_completed() triggers inconsistent
accounting, there's also high chances that the thaw call will be
unexpected at this time too, which will lead to a g_error().
This makes mutter more lenient to effect_completed() calls of the
right type (i.e. those triggering freeze/thaw) being performed more
times than necessary in the upper parts. A warning will be issued,
but the process won't abort.
https://bugzilla.gnome.org/show_bug.cgi?id=777691
Not having a surface actor would cause the window actor state to be
considered frozen, thus causing various state (such as geometry, shape
etc) synchronization to be delayed until thawed. If the window actor
was "thawed" due to having a surface set, not all state would be
properly synchronized, causing the thawed window actor to be displayed
incorrectly.
This patch fixes this by putting state synchronization after thawing in
a common function, calling it both from frozen count decreasing and
surface setting.
This fixes for example misplaced menus in Steam.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
Instead of assuming there is a single onscreen framebuffer, use the
helper functions for setting the frame callback and getting the frame
counter.

Before this commit, on Wayland, the buffer rect would have the size of
the attached Wayland buffer, no matter the scale. The scale would then
be applied ad-hoc by callers when a sane rectangle was needed. This
commit changes buffer_rect to rather represent the surface rect (i.e.
what is drawn on the stage, including client side shadow). The users of
buffer_rect will no longer need to scale the buffer_rect themself to
get a usable rectangle.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as
fatal :-(
That's clearly unwanted for a compositor, so make sure to always pass
an error parameter where a runtime error is possible (i.e. any CoglError
that is not a malformed blend string).
https://bugzilla.gnome.org/show_bug.cgi?id=765058
Some windows, like Chromium and Steam, are technically CSD in that they
don't want a system titlebar and draw their own, but we should still
provide them with a shadow.
We may access it during painting even if it has been freed. For now,
manually unset it during the MetaWaylandSurface cleanup; in the future
make MetaWaylandSurface a GObject and make the surface pointer a weak
reference.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
The elementary guys would like this as an API, and I don't see any
reason to refuse -- this is quite nice shadow painting code :)
For some reason, gobject-introspection can't seem to cope with
MetaWindowShape. I'll look into it a bit later, but for now, mark
the function it has trouble with as (skip).
