The model API was an ad hoc addition to Clutter, back in the 0.6 days,
that was needed because GLib did not offer anything of sort, and the
only model-like storage was inside GTK+. The API design was heavily
based on GtkTreeModel and friends, with column-based collections of
generic data.
Since then, the model API inside Clutter has not really been integrated
in the core API; on the other hand, GIO has grown a model API, and it's
seeing more use in the platform.
This means that the ClutterModel API should finally be deprecated, and
we should move code to the GListModel API inside GIO.
Like we do for X11, GDK, MacOS, and Windows, the Wayland backend can be
autodetected. We should only fail if the Wayland support was explicitly
asked at configure time, but the dependencies were not satisfied.
Certain crossing modes notify about synthesized events, where
the pointer didn't really leave the window. Unsetting the stage
from the device at that time is incorrect, and will leave all
remaining touches unable to pick coordinates, so silently eaten
away.

Straight from Cogl.
This allows us to propagate the GdkVisual Cogl and Clutter use to
embedding toolkits, like GTK+.
The function is annotated as being added to the 1.22 development
cycle because it will be backported to the stable branch, so that
downstream developers can package up a version of Clutter that does
not crash on nVidia.

GDK 3.16 started selecting different visuals, to best comply with the
requirements for OpenGL, and this has broken Clutter on GLX drivers that
are fairly picky in how they select visuals and GLXFBConfig.
GDK selects GLXFBConfig that do not include depth or stencil buffers;
Cogl, on the other hand, needs both depth and stencil buffers, and keeps
selecting the first available visual, assuming that the GLX driver will
give us the best compliant one, as per specification. Sadly, some
drivers will return incompatible configurations, and then bomb out when
you try to embed Clutter inside GTK+, because of mismatched visuals.
Cogl has an old, deprecated, Clutter-only API that allows us to retrieve
the XVisualInfo mapping to the GLXFBConfig it uses; this means we should
look up the GdkVisual for it when creating our own GdkWindows, instead
of relying on the RGBA and system GdkVisuals exposed by GDK — at least
on X11.

In order to do device matching we need to propagate more information,
like the device_id (only on X11 with the XInput2 extension enabled),
the vendor id, and the product id.

When defining clutter_stage_gdk_update_foreign_event_mask, check for the
same macros as when actually using it.

Its ::gesture-end implementation used to check the press/release
coordinates for the first touchpoint. On multifinger swipes, we
can receive this vfunc called due to other touch sequence going
first, so we'd get 0/0 as the release coordinates for this still
active sequence, resulting in bogus directions.
Instead, check the last event coordinates, that will be always
correct regardless of whether the touchpoint 0 finished yet or
not.

It's pretty much pointless to have two API references:
• the Cally API reference is fairly small
• the build system is already complicated as it is
• GTK-Doc isn't smart enough to ignore sub-directories
• Cally is not a separate library, just a separate namespace
There are some issues with GTK-Doc not accepting multiple namespaces,
but nothing seriously tragic.
Commit 79849ef1d5fff9acd310cd68d59df0c7cf2cb28f had a typo in the
device property format check. This property is formated in 8-bit
items, not 32-bit.
This went unnoticed till now because some touchpads were still being
detected as such due to a second check below:
else if (strstr (name, "touchpad") != NULL)
source = CLUTTER_TOUCHPAD_DEVICE;

It could happen that gdk_screen_get_setting fails to retreive
Gdk/WindowScalingFactor which leads to the following warnings when
clutter_init is called:
GLib-GObject-WARNING **: value "0" of type 'gint' is invalid or out of range for property 'window-scaling-factor' of type 'gint'
GLib-GObject-WARNING **: value "0" of type 'gint' is invalid or out of range for property 'dnd-drag-threshold' of type 'gint'

Slightly edited to fix up whitespace issues.

The paint opacity for a top level is always overridden to be the full
value, since it's a composited value and we want to paint our scene.
When clearing the stage framebuffer, though, we want to use the actual
opacity, if ClutterStage:use-alpha is set.
-1 is explicitly an invalid value to pass to eglSwapBuffersWithDamage,
and the specification admits as much:
If
eglSwapBuffersWithDamageEXT is called and <n_rects>, is less
than zero or <n_rects> is greater than zero but <rects> is
NULL, EGL_BAD_PARAMETER is generated.
Fix up our usage of SwapBuffersWithDamage to match the behavior in the
EGL specification.

These are just terrible API that we've been stringing along since the
0.x days. We cannot truly deprecate them, because they are, in some
cases, the only actual API to perform some operation, and porting all
the code in the world is not going to make us any friends.
For the time being, we use a deprecation notice in the documentation.
The macros are useless for language bindings, and are terribly unsafe
from C as well. There's always the option of using the GObject
properties they refer to, but it's more efficient to just have a simple
getter function.
