9db135c4ef glx: Clean up sync-to-vblank mechanism discovery
The code has gotten really complicated to follow.

As soon as we have a sync-to-vblank mechanism we should just bail out.

Also, __GL_SYNC_TO_VBLANK (which is used by nVidia) should be assumed
equivalent to a CLUTTER_VBLANK_GLX_SWAP.

655cb966c0 docs: Add visual cue for Animator's key frames
We should explain what a "key frame" is for ClutterAnimator, possibly
with some sort of visual cue.

This allows me to demonstrate my poor skills at using Inkscape, as well
as my overall bad taste for graphics design.

d3d05261e6 script-parser: Remove top-level types list
The top-level types list was comically out of date, and it was only
determining whether the type we were constructing was initially unowned
or a full object. We can safely replace it with a simple type check.

4bc4c604e9 box: Let pack_at() create the ChildMeta, if any
A sub-class of ClutterBox might add ChildMeta support, and since
pack_at() does not go through clutter_container_add_actor(), we
need to manually call the create_child_meta() ourselves.

543e2d3f06 container: Expose create and destroy ChildMeta methods
It is conceivable that Container implementations might add children
outside of the Container::add() implementation - e.g. for packing at
a specific index. Since the addition (and removal) might happen outside
the common path we need to expose all the API that is implicitly called
by ClutterContainer when adding and removing a child - namely the
ChildMeta creation and destruction.

14999bec5e gles2: Remove the special wrapper for glBindTexture
Previously the GLES2 backend needed a special wrapper for
glBindTexture because it needed to know the internal GL format of the
texture in order to correctly implement the GL_MODULATE texture env
mode. When GL_MODULATE is used then the RGB values are taken from the
previous texture layer rather than being fetched from the
texture. However since the material API was added Cogl no longer uses
the GL_MODULATE texture env mode but instead always uses GL_COMBINE.

Compiling the GLES2 backend broke since the more-texture-backends
branch merge because the cogl_get_internal_gl_format function was
removed and there was one place in GLES2 specific code that was using
this to bind the texture.

eba07020c5 cogl-gles2-wrapper: Add support for the layer combine operations
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.

26e22b2ede Conditionally use G_VALUE_COLLECT_INIT() macro
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.

d1ca0e1b8f fixed layout: Store a back pointer to the Container
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.

523bab0868 layout: allow wider use of the CLUTTER_ACTOR_NO_LAYOUT flag
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.

eb35c446b1 clutter-box: Layer new actors on top of all others at the same depth
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.

da0315e4d6 box: Revert "Tweak the depth sorting function"
This reverts commit 939e56e2b1.

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.

This patch simply fixes a few cases where we weren't using G_UNLIKELY.

511e5ceb51 cogl debug: Makes COGL_DEBUG=all|verbose|help more useful
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.

a9941e9499 debug: Split debugging notes from behavioural modifiers
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.

5ed4732737 device: Force ENTER on Stage with overlapping Actors
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.

ee33357fd5 stage: Only clutter_stage_get_default() creates the default stage
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.

9c06c94374 cogl-texture: for foreign textures; always trust user geom
We now never query the width and height of the given texture object
from OpenGL. The problem is that the user may be creating a Cogl

never called and the texture_from_pixmap spec doesn't clarify that
it's reliable to query the width from OpenGL.

51a3e49c82 device: Allow updating devices from embedding toolkits
Embedding toolkits most likely will disable the event handling, so all
the input device code will not be executed. Unfortunately, the newly
added synthetic event generation of ENTER and LEAVE event pairs depends
on having input devices.

In order to unbreak things without reintroducing the madness of the
previous code we should allow embedding toolkits to just update the
state of an InputDevice by using the data contained inside the
ClutterEvent. This strategy has two obvious reasons:

  • the embedding toolkit is creating a ClutterEvent by translating
    a toolkit-native event anyway

  • this is exactly what ClutterStage does when processing events

We are, essentially, deferring input device handling to the embedding
toolkits, just like we're deferring event handling to them.
