43efab46bc Intial Re-layout of the Cogl source code and introduction of a Cogl Winsys
As part of an incremental process to have Cogl be a standalone project we
want to re-consider how we organise the Cogl source code.

Currently this is the structure I'm aiming for:
cogl/
    cogl/
	<put common source here>
	winsys/
	   cogl-glx.c
	   cogl-wgl.c
	driver/
	    gl/
	    gles/
	os/ ?
    utils/
	cogl-fixed
	cogl-matrix-stack?
        cogl-journal?
        cogl-primitives?
    pango/

The new winsys component is a starting point for migrating window system
code (i.e.  x11,glx,wgl,osx,egl etc) from Clutter to Cogl.

The utils/ and pango/ directories aren't added by this commit, but they are
noted because I plan to add them soon.

Overview of the planned structure:

* The winsys/ API is the API that binds OpenGL to a specific window system,
  be that X11 or win32 etc.  Example are glx, wgl and egl. Much of the logic
  under clutter/{glx,osx,win32 etc} should migrate here.

* Note there is also the idea of a winsys-base that may represent a window
  system for which there are multiple winsys APIs.  An example of this is
  x11, since glx and egl may both be used with x11.  (currently only Clutter
  has the idea of a winsys-base)

* The driver/ represents a specific varient of OpenGL. Currently we have "gl"
  representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing
  GLES 1.1 (fixed funciton) and 2.0 (fully shader based)

* Everything under cogl/ should fundamentally be supporting access to the
  GPU.  Essentially Cogl's most basic requirement is to provide a nice GPU
  Graphics API and drawing a line between this and the utility functionality
  we add to support Clutter should help keep this lean and maintainable.

* Code under utils/ as suggested builds on cogl/ adding more convenient
  APIs or mechanism to optimize special cases. Broadly speaking you can
  compare cogl/ to OpenGL and utils/ to GLU.

* clutter/pango will be moved to clutter/cogl/pango

How some of the internal configure.ac/pkg-config terminology has changed:
backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11"
backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la"
clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx"
CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS
clutterbackendlib -> CLUTTER_WINSYS_LIB
CLUTTER_COGL -> COGL_DRIVER # e.g. "gl"

Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps

As the first thing to take advantage of the new winsys component in Cogl;
cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into
cogl/common/cogl.c and this common implementation first trys
_cogl_winsys_get_proc_address() but if that fails then it falls back to
gmodule.

15d7a86621 [backends] Remove the idea of offscreen stages from all backends
The only backend that tried to implement offscreen stages was the GLX backend
and even this has apparently be broken for some time without anyone noticing.

The property still remains and since the property already clearly states that
it may not work I don't expect anyone to notice.

This simplifies quite a bit of the GLX code which is very desireable from the
POV that we want to start migrating window system code down to Cogl and the
simpler the code is the more straight forward this work will be.

In the future when Cogl has a nicely designed API for framebuffer objects then
re-implementing offscreen stages cleanly for *all* backends should be quite
straightforward.

94b35a4a5e [build] GCC_FLAGS is no more, MAINTAINER_CFLAGS is the One.
CC_FLAGS was a left over from the 0.8.x age. Killed it and use the

6d9498da7c Adds a cogl_flush() to give developers breaking into raw GL a fighting chance
This function should only need to be called in exceptional circumstances
since Cogl can normally determine internally when a flush is necessary.

As an optimization Cogl drawing functions may batch up primitives
internally, so if you are trying to use raw GL outside of Cogl you stand a
better chance of being successful if you ask Cogl to flush any batched
geometry before making your state changes.

cogl_flush() ensures that the underlying driver is issued all the commands
necessary to draw the batched primitives.  It provides no guarantees about
when the driver will complete the rendering.

This provides no guarantees about the GL state upon returning and to avoid
confusing Cogl you should aim to restore any changes you make before
resuming use of Cogl.

If you are making state changes with the intention of affecting Cogl drawing
primitives you are 100% on your own since you stand a good chance of
conflicting with Cogl internals.  For example clutter-gst which currently
uses direct GL calls to bind ARBfp programs will very likely break when Cogl
starts to use ARBfb programs internally for the material API, but for now it
can use cogl_flush() to at least ensure that the ARBfp program isn't applied
to additional primitives.

This does not provide a robust generalized solution supporting safe use of
raw GL, its use is very much discouraged.

845ff67301 [cogl] Improving Cogl journal to minimize driver overheads + GPU state changes
Previously the journal was always flushed at the end of
_cogl_rectangles_with_multitexture_coords, (i.e.  the end of any
cogl_rectangle* calls) but now we have broadened the potential for batching
geometry.  In ideal circumstances we will only flush once per scene.

In summary the journal works like this:

When you use any of the cogl_rectangle* APIs then nothing is emitted to the
GPU at this point, we just log one or more quads into the journal.  A
journal entry consists of the quad coordinates, an associated material
reference, and a modelview matrix.  Ideally the journal only gets flushed
once at the end of a scene, but in fact there are things to consider that
may cause unwanted flushing, including:

- modifying materials mid-scene
    This is because each quad in the journal has an associated material
    reference (i.e. not copy), so if you try and modify a material that is
    already referenced in the journal we force a flush first)

    NOTE: For now this means you should avoid using cogl_set_source_color()
	      since that currently uses a single shared material. Later we
	  should change it to use a pool of materials that is recycled
	  when the journal is flushed.

- modifying any state that isn't currently logged, such as depth, fog and
  backface culling enables.

The first thing that happens when flushing, is to upload all the vertex data
associated with the journal into a single VBO.

We then go through a process of splitting up the journal into batches that
have compatible state so they can be emitted to the GPU together.  This is
currently broken up into 3 levels so we can stagger the state changes:

1) we break the journal up according to changes in the number of material layers
   associated with logged quads. The number of layers in a material determines
   the stride of the associated vertices, so we have to update our vertex
   array offsets at this level. (i.e. calling gl{Vertex,Color},Pointer etc)
2) we further split batches up according to material compatability. (e.g.
   materials with different textures) We flush material state at this level.
3) Finally we split batches up according to modelview changes. At this level
   we update the modelview matrix and actually emit the actual draw command.

This commit is largely about putting the initial design in-place; this will be
followed by other changes that take advantage of the extended batching.

c6fba47a52 Hide clutter_context_get_default()
The clutter_context_get_default() function is private, but shared
across Clutter. For this reason, it should be prefixed by '_' so
that the symbol is hidden from the shared object.

7c89a0ccfa [stage] Rename :fullscreen to :fullscreen-set
The :fullscreen property is very much confusing as it is implemented.
It can be written to a value, but the whole process might fail. If we
set:

  g_object_set (stage, "fullscreen", TRUE, NULL);

and the fullscreen process fails or it is not implemented, the value
will be reset to FALSE (if we're lucky) or left TRUE (most of the
times).

The writability is just a shorthand for invoking clutter_stage_fullscreen()
or clutter_stage_unfullscreen() depending on a boolean value without
using an if.

The :fullscreen property also greatly confuses high level languages,
since the same symbol is used:

  - for a method name (Clutter.Stage.fullscreen())
  - for a property name (Clutter.Stage.fullscreen)
  - for a signal (Clutter.Stage::fullscreen)

For these reasons, the :fullscreen should be renamed to :fullscreen-set
and be read-only. Implementations of the Stage should only emit the
StageState event to change from normal to fullscreen, and the Stage
will automatically update the value of the property and emit a notify
signal for it.

d28c9e5db1 Remove unnecessary setting of CLUTTER_ACTOR_REALIZED flag
An implementaton of realize() never needs to set the
CLUTTER_ACTOR_REALIZED flag, though it can unset the flag if
things fail unexpectedly. (Previously, stage backend implementations
had to do this since clutter_actor_realize() wasn't used; this
is no longer the case.)

0187bb3965 [actor] Use flags to control allocations
Instead of passing a boolean value, the ::allocate virtual function
should use a bitmask and flags. This gives us room for expansion
without breaking API/ABI, and allows to encode more information to
the allocation process instead of just changes of absolute origin.

d6d208da7d Remove Units from the public API
With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.

ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.

So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:

  - we have to maintain twice the amount of entry points in ClutterActor
  - we still do an integer-to-float implicit conversion
  - we introduce a weird impedance between pixels and "pixels with
    fractionary bits"
  - language bindings will have to choose what to bind, and resort
    to manually overriding the API
    + *except* for language bindings based on GObject-Introspection, as
      they cannot do manual overrides, thus will replicate the entire
      set of entry points

For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:

  void clutter_actor_set_x (ClutterActor *self,
                            gfloat        x);
  void clutter_actor_get_size (ClutterActor *self,
                               gfloat       *width,
                               gfloat       *height);
  gfloat clutter_actor_get_height (ClutterActor *self);

etc.

The issues I have identified are:

  - we'll have a two cases of compiler warnings:
    - printf() format of the return values from %d to %f
    - clutter_actor_get_size() taking floats instead of unsigned ints
  - we'll have a problem with varargs when passing an integer instead
    of a floating point value, except on 64bit platforms where the
    size of a float is the same as the size of an int

To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:

  - we remove ambiguity in the API with regard to pixels and units
  - we remove entry points we get to maintain for the whole 1.0
    version of the API
  - we make things simpler to bind for both manual language bindings
    and automatic (gobject-introspection based) ones
  - we have the simplest API possible while still exposing the
    capabilities of the underlying GL implementation

125bded814 Enforce invariants on mapped, realized, visibility states
Bug 1138 - No trackable "mapped" state

* Add a VISIBLE flag tracking application programmer's
  expected showing-state for the actor, allowing us to
  always ensure we keep what the app wants while tracking
  internal implementation state separately.

* Make MAPPED reflect whether the actor will be painted;
  add notification on a ClutterActor::mapped property.
  Keep MAPPED state updated as the actor is shown,
  ancestors are shown, actor is reparented, etc.

* Require a stage and realized parents to realize; this means
  at realization time the correct window system and GL resources
  are known. But unparented actors can no longer be realized.

* Allow children to be unrealized even if parent is realized.
  Otherwise in effect either all actors or no actors are realized,
  i.e. it becomes a stage-global flag.

* Allow clutter_actor_realize() to "fail" if not inside a toplevel

* Rework clutter_actor_unrealize() so internally we have
  a flavor that does not mess with visibility flag

* Add _clutter_actor_rerealize() to encapsulate a somewhat
  tricky operation we were doing in a couple of places

* Do not realize/unrealize children in ClutterGroup,
  ClutterActor already does it

* Do not realize impl by hand in clutter_stage_show(),
  since showing impl already does that

* Do not unrealize in various dispose() methods, since
  ClutterActor dispose implementation already does it
  and chaining up is mandatory

* ClutterTexture uses COGL while unrealizable (before it's
  added to a stage). Previously this breakage was affecting
  ClutterActor because we had to allow realize outside
  a stage. Move the breakage to ClutterTexture, by making
  ClutterTexture just use COGL while not realized.

* Unrealize before we set parent to NULL in clutter_actor_unparent().
  This means unrealize() implementations can get to the stage.
  Because actors need the stage in order to detach from stage.

* Update clutter-actor-invariants.txt to reflect latest changes

* Remove explicit hide/unrealize from ClutterActor::dispose since
  unparent already forces those
  Instead just assert that unparent() occurred and did the right thing.

* Check whether parent implements unrealize before chaining up
  Needed because ClutterGroup no longer has to implement unrealize.

* Perform unrealize in the default handler for the signal.
  This allows non-containers that have children to work properly,
  and allows containers to override how it's done.

* Add map/unmap virtual methods and set MAPPED flag on self and
  children in there. This allows subclasses to hook map/unmap.
  These are not signals, because notify::mapped is better for
  anything it's legitimate for a non-subclass to do.

ee6145c795 Set the mapped flag on the stage in the SDL and eglnative backends
Bug 1493 - GL ES does not work since Jan 9 in PowerVR SGX 535, Intel

The mapped flag needs to be set on the stage otherwise
clutter_actor_queue_redraw will never queue a redraw and never draw
anything.

In these two backends there is not really a way to hide the stage so
they both set the mapped flag immediatly when clutter_actor_show is
called.

Rework the stage wrapper/implementation relation: remove

277d86f654 Preserve ordering when placing synthetic events in the queue
When we are in the the event translation function sometimes we need to
synthesise events: the double and triple click events are synthetic events
placed on the queue after a sequence of events has been received, for
instance.

Until now, the events were placed on the queue after the translation from
the native events was successful. This led to a loss of ordering because
we put the synthesised event on the queue before the last event that
triggered it.

This patch puts the events on the queue before translating them, with a
"pending" flag set; if the translation sequence is completed then the flag
is removed - otherwise the event is removed from the queue altogether. The
queue manipulation functions have been modified to ignore the "pending"
flag when looking for events.

This patch also adds a private structure overlayed on the ClutterEvent
struct so that we can extend the events with private data without exposing
it in the public API.
