We guarantee ourselves that a valid pixmap will appear any time
that the window is painted. The window actor will be scheduled
for a repaint if it's added / removed from the scene graph, like
during construction, if the size changes, or if we receive damage,
which are the existing use cases where this function is called.
So, I can't see any reason that we queue a redraw in here.
With the split into surface actors, we don't have an easy place
we can use to queue a redraw, and since it's unnecessary, we can
just drop it on the floor.

Compositors haven't been able to manage more than one screen for
quite a while. Merge MetaCompScreen into MetaCompositor, and update
the API to match.
We still keep MetaScreen in the public compositor API for compatibility
purposes.
We previously separated out MetaDisplay and MetaScreen. mutter
would only manage one screen, but we still kept a list of screens
for simplicity.
With Wayland support, we no longer care about the ability to
manage more than one screen at a time. Remove this by killing
the list of screens, in favor of having just one MetaScreen
in MetaDisplay.
We also kill off active_screen at the same time, since it's
not necessary anymore.
A future cleanup should merge MetaDisplay and MetaScreen. To avoid
breaking API, we should probably keep MetaScreen around as a dummy
type.
I'm a bit tired of hearing about this when I launch mutter-wayland
nested. Ideally, this would be part of display server integration,
not GNOME integration, so we could simply not make the call when
nested, but oh well.
cogl_texture_get_components can be used on both X11 and Wayland
backends. Technically, the detection is different: we actually
check the actual RENDER format in the old code, while Cogl simply
assumes that any pixmap with a depth >= 32 is ARGB32. Since Cogl
already seems to be working with its internal checks, it makes
more sense to use Cogl's check rather than keeping our own.
is_argb32 can be called at any time, including times when we don't
have a texture. In that case, just assume we're ARGB32. The value
really shouldn't be important though.
On 64-bit fedora the 32-bit MinGW compiler is called
i686-w64-mingw32-gcc which wasn't being picked up by the
mingw-fetch-depdencies script.

This macro is internal to gobject so using it risks breaking Cogl if
glib changes its API. Instead we just use its expansion. Note that
glib provides two expansions for this depending on the glib version
but this only uses the one for older versions.

cogl_gst_video_sink_get_natural_size was using g_return_val_if_fail
but its return type is void. For some reason GCC doesn't complain
about this but it causes a compile error on clang.
The pkg-config file might not necessarily be installed yet so I don't
think it makes sense to try and include it when running g-ir-scanner.
Presumably it should pick up the headers from source directory instead
of the installed directory. It seems to build without this patch so
let's just revert it.
This reverts commit d9c8570f14a43e6c3a48c521e819427f02e816e4.
When I refactored this out into a vfunc, I forgot to change the
code that interprets the result flags to actually respect the
new FRAME_SHAPE_CHANGED result flag.
Since we weren't ever clearing the frame bounds, this meant that
the "shadow clip" wasn't ever updated as a result. Since right now
all Wayland surfaces are considered ARGB32, we always clip shadows
under frames, and thus shadows had this weird "punch-out" from the
first frame shape.
While the ICCCM mandates the use of this, it's not necessary under
a composited environment from my understanding, and it's a flat
out no-op under XWayland.
Looking at the other rootless servers like Xwin/Xquartz, it seems
that they contain code for colormap emulation, but they're actually
never used -- a bug prevents the code from ever being called. Given
that it's been this way since 2003, I'm going to hazard a guess that
not many apps using colormaps. Kill them off.
display.c is getting a bit crowded. Move most of the handling
out to another file, events.c.
The long-term goal is to have generic event handling here, with
backend-specific handling for the types of windows and such.
