The texture layer combine functions are now hard coded to GL_COMBINE
instead of GL_MODULATE. The combine function can be customized with
all the parameters of GL_COMBINE. A shader is generated to implement
the given parameters.
Currently it will try to generate code for the constant color but it
will use a uniform which does not exist.
The GLES2 backend for Cogl is failing to compile because
GL_MAX_TEXTURE_UNITS is not defined. Let's define it and provide a
wrapper which uses GL_MAX_TEXTURE_IMAGE_UNITS or
COGL_GLES2_MAX_TEXTURE_UNITS, whichever is the smallest.
A bogus ClutterInterpolation argument had been carried from
clutter_animator_set_interpolation to clutter_animator_get_interpolation
in copy and paste.
GLib 2.24 (but starting from the 2.23.2 unstable release) added a new
macro for collecting GValues from a va_list.
The newly added G_VALUE_COLLECT_INIT() macro should be used in place
of initializing the GValue and calling G_VALUE_COLLECT(), and improves
the collection performances by avoiding multiple checks, free and
initialization calls.
The installed _HEADERS should be the public ones and the enumeration
types; repeating clutter-x11-texture-pixmap.h breaks with automake 1.11
and doesn't strictly make any sense.

When set_container() is called with a NULL container we cannot use the
passed pointer to unset the CLUTTER_ACTOR_NO_LAYOUT flag. We should
store a back pointer to the container as object data (there's no need
to add a Private data structure in this case) and unset the flag on the
back pointer instead.
We need to make the Stage set the MAPPED flag on itself if we want to
verify the MAPPED state. That was always the case - it just worked
before because the Stage was shown at least once.
Previously only ClutterGroup was able to set the CLUTTER_ACTOR_NO_LAYOUT
flag which allows clutter-actor.c to avoid a relayout when showing or
hiding fixed layout containers. Instead of it being the responsibility
of the container to set this flag this patch makes the layout manager
itself decide in the ::set_container method. This way both ClutterBox
and ClutterGroup can take advantage of the optimization.
The NEWS file was not updated for the 1.1.12 release, so we need to
update it now.
The Release Notes section for Clutter and Cogl also needs some more
entries that escaped previous releases.
g_list_insert_sorted inserts the new actor before all others that
compare equal so for the normal case when all actors have depth==0
this has the surprising behaviour of layering the actors in reverse
order. To fix this it now manually inserts the actor in the right
place by searching until it finds an actor at a higher depth and
inserting before that.

This reverts commit 939e56e2b12e5c96fa1173be33c2786ddfe57c25.
Changing the depth sort function to have inconsistent behaviour for
nodes that compare equal breaks the stability of g_list_sort. It ends
up so that every time clutter_container_sort_depth_order is called the
order of all actors with the same depth is reversed.

To aid in the debugging of Clutter stage resize issues this adds a
COGL_DEBUG=opengl option that will trace "some select OpenGL calls"
(currently just glViewport calls)

Most Cogl debugging code conditions are marked as G_UNLIKELY with the
intention of having the CPU branch prediction always assume the
path is disabled so having debugging support in release binaries has
negligible overhead.
This patch simply fixes a few cases where we weren't using G_UNLIKELY.

We basically want all Clutter applications out in the wild to at least
have the basic set of COGL_DEBUG/--cogl-debug options available for
investigating issues.
COGL_DEBUG=all wasn't previously useful as there are several options
that change the behaviour of Cogl and all together wouldn't help anyone
debug anything.
This patch makes it so COGL_DEBUG=all|verbose now only enables options
that don't change the behaviour of Cogl, i.e. they only affect the
amount of noise we'll print to a terminal.
In addition to that this patch also improves the output from
COGL_DEBUG=help so we now print a table of options including one liner
descriptions of what each option enables.

Some of the ClutterDebugFlags are not meant as a logging facility: they
actually change Clutter's behaviour at run-time.
It would be useful to have this distinction ratified, and thus split
ClutterDebugFlags into two: one DebugFlags for logging facilities and
another set of flags for behavioural changes.
This split is warranted because:
• it should be possible to do "CLUTTER_DEBUG=all" and only have
log messages on the output
• it should be possible to use behavioural modifiers even on a
Clutter that has been compiled without debugging messages
support
The commit adds two new debugging flags:
ClutterPickDebugFlags - controlled by the CLUTTER_PICK environment
variable
ClutterPaintDebugFlags - controlled by the CLUTTER_PAINT environment
variable
The PickDebugFlags are:
nop-picking
dump-pick-buffers
While the PaintDebugFlags is:
disable-swap-events
The mechanism is equivalent to the CLUTTER_DEBUG environment variable,
but it does not depend on the debug level selected when configuring and
compiling Clutter. The picking and painting debugging flags are
initialized at clutter_init() time.

The motion event compression should be affected by the device field of
the event; that is: we should compress motion events coming from the
same device.
If an actor is on the boundary of a Stage and the pointer for a device
enters the Stage over that actor, the sequence of events currently is:
➔ ENTER (source: actor, related: NULL)
➔ MOTION
Thus the Stage never gets an ENTER event. This is a regression from
Clutter 1.0.
The correct sequence is:
➔ ENTER (source: stage, related: NULL)
➔ ENTER (source: actor, related: stage)
➔ MOTION
This also maps to the sequence of events sythesized by Clutter when
leaving the Stage through an actor overlapping the Stage boundary.

The change to reduce GConf trips by using
gconf_client_all_entries() broke the fallback to builtin values
because update_binding() was no longer called for bindings not
found in GConf. Fix this by keeping track of the bindings we
find from GConf in a hash table, then looping through and setting
all the bindings at the end.
This also improves efficiency by avoiding a linear scan for each
binding in GConf.
https://bugzilla.gnome.org/show_bug.cgi?id=609710
When we are reading bindings initially, update_list_binding() needs
to be passed the correct "string list type" since we are calling
it with a list of strings instead of a list of GConfValue.

The introduction of the StageManager in 0.8 implied that the first Stage
instance to be created was automatically assigned the status of "default
stage". This was all well and good, since the default stage was created
behind the curtains by the initialization sequence.
Now that the initialization sequence does not create a default stage any
longer, it means that the first stage created using clutter_stage_new()
gets to be the default, and all special and warm and fuzzy - which also
means that the first stage created by clutter_stage_new() cannot be
destroyed or handled as any other stage. Whoopsie.
Let's go back to the old semantics: the stage created by the first
invocation of clutter_stage_get_default() is the default stage, and
nothing else can be set as default. One day we'll be able to break the
API and the whole default stage business will be a thing of the past.
Embedding toolkits should benefit from a proper documentation of
clutter_input_device_update_from_event(): its meaning, its use and
the caveats for the "update_stage" argument.
