I always have to think twice before returning a value from an event
signal handler, and I've been writing them for the past 10 years, so
it's conceivable that application developers that start with Clutter
will find them confusing as well.
Simple symbolic names should be easier to use.
The depth cueing through GL fog has been broken for a long while, now.
The fog-related API in Clutter is ridiculously limited, and harks back
to simpler times; the ClutterFog structure is not enough to express all
the GL fog machinery, and required application code to connect to the
Stage's paint implementation and drop into Cogl directly.
Additionally, the fixed pipeline fog machinery in GL simply does not
work with premultiplied alpha, unless you use a shader - and in that
case it would only work for textures. Let's deprecate it, and just
don't do anything if somebody has the brilliant idea of setting the
:use-fog property to TRUE.
Sadly, we need to remove the G_GNUC_NULL_TERMINATED annotation from
ClutterBox packing API; the compiler will otherwise emit a warning
for perfectly legal statements like:
clutter_box_pack (box, child, NULL);
because of the missing sentinel.
See also: g_object_new().
GLib has a "diagnostic mode" switch that can be checked to enable debug
messages on deprecated properties and signals, as these are purely
run-time constructs, and as such cannot be caught by compiler warnings.
The diagnostic mode is toggled by a simple environment variable, and
can be used to ease porting of application code.
We can use something similar to mark deprecated virtual functions and
other run-time constructs; to avoid collisions, we should use our own
environment variable, CLUTTER_ENABLE_DIAGNOSTIC.
Instead of using a PaintVolume for a 2D region, and an internal
function, use the newly added queue_redraw_with_clip() method.
This removes the last bit of internal API usage in the
ClutterX11TexturePixmap actor.

Add a public version of the clipped queue redraw, using a 2D clip. This
allows implementing actors with trackable 2D clipped regions, like the
ClutterX11TexturePixmap, outside of Clutter itself.

The Wayland protocol now has events represent when a pointer enters the
surface and when it leaves again.
For leaves the surface is not set in the event, for enters the surface is set.
Simply use this to determine whether to emit CLUTTER_ENTER or CLUTTER_LEAVE.
Previously the wl_shell object held the methods that allowed a client to
request changes to the shell's state associated with a surface. These methods
have now been moved to a wl_shell_surface object.
This change allows configure events to be handled inside the stage rather than
the backend.
When clutter has been built with Wayland compositor support then we now
expose a public CLUTTER_HAS_WAYLAND_COMPOSITOR_SUPPORT define so that
applications can #ifdef code that depends on the api that this feature
implies.

and the wayland device manager private so we don't get symbol collisions

This updates the evdev input backend code to compile and also updates
the code to not refer to the default stage and instead check for a
stage to be associated with the input device. If no stage is currently
associated with a device generating events then the events are dropped
on the floor.

This adds internal api to be able to query the stage currently
associated with a given input device so input backends shouldn't need to

This adds an extremely minimal wayland compositor to tests/interactive
to test the ClutterWaylandSurface actor. Currently this minimal
compositor doesn't support any input, it simply paints client surfaces
fixed at the top-left of the stage.

This adds a --enable-wayland-compositor configure option which will add
support for a ClutterWaylandSurface actor which can be used to aid in
writing Wayland compositors using Clutter by providing a ClutterActor to
represent Wayland client surfaces.
Notably this configure option isn't tied into any particular backend
since conceptually the compositor support can be used in conjunction
with any clutter backend that has corresponding Cogl support.

This updates Wayland support in line with upstream changes to the Wayland
API and protocol.
This update means we no longer use the Cogl stub winsys so a lot of code
that had to manually interact with EGL and implement a swap_buffers
mechanism could be removed and instead we now depend on Cogl to handle
those things for us.
This update also adds an input device manager consistent with other
clutter backends.
Note: to use the client side "wayland" clutter backend you need to have
built Cogl with --enable-wayland-egl-platform. If Cogl has been built
with support for multiple winsys backends then you should run
applications with COGL_RENDERER=EGL in the environment.
