e26a59afc8 EGL: Updates GDL platform support
The GDL API is used for example on intel ce4100 (aka Sodaville) based
systems as a way to allocate memory that can be composited using the
platforms overlay hardware. This updates the Cogl EGL winsys and the
support in Clutter so we can continue to support these platforms.

c55cffbb6b Moves all EGL code down from Clutter to Cogl
As was recently done for the GLX window system code, this commit moves
the EGL window system code down from the Clutter backend code into a
Cogl winsys.

Note: currently the cogl/configure.ac is hard coded to only build the GLX
winsys so currently this is only available when building Cogl as part
of Clutter.

532b563439 Add temporary cogl-clutter.h to aid splitting out Cogl
This gives us a way to clearly track the internal Cogl API that Clutter
depends on. The aim is to split Cogl out from Clutter into a standalone
3D graphics API and eventually we want to get rid of any private
interfaces for Clutter so its useful to have a handle on that task.
Actually it's not as bad as I was expecting though.

e381a159a7 Remove unused _cogl_swap_buffers_notify
Recently _cogl_swap_buffers_notify was added (in 142b229c5c) so that
Cogl would be notified when Clutter performs a swap buffers request for
a given onscreen framebuffer. It was expected this would be required for
the recent cogl_read_pixel optimization that was implemented (ref
1bdb0e6e98) but in the end it wasn't used.

Since it wasn't used in the end this patch removes the API.

56d133f908 backend: Move event translators to the base class
In the future, we want event translators to be the way to handle events

ClutterBackend class, and not an X11-only concept.

224280be22 backend: Invoke ClutterStageWindow::redraw by default
Instead of asking all backends to do that for us, we can call
ClutterStageWindow::redraw ourselves by default.

This changeset fixes all backends to actually do the right thing, and
move the stage implementation redraw inside the ClutterStageWindow
implementation itself.

acf51259d2 x11: Store a back pointer to the backend in the stage
Since we access it in order to get the X11 Display pointer, it makes
sense to have the ClutterBackendX11 already available inside the
ClutterStageX11 structure, and avoid the pattern:

  ClutterBackend *backend = clutter_get_default_backend ();
  ClutterBackendX11 *backend_x11 = CLUTTER_BACKEND_X11 (backend);

which costs us a function call, a type cast and an unused variable.

142b229c5c cogl: Adds _cogl_swap_buffers_notify for clutter backends
This adds a stop-gap mechanism for Cogl to know when the window system
is requested to present the current backbuffer to the frontbuffer by
adding a _cogl_swap_buffers_notify function that backends are now
expected to call right after issuing the equivalent request to OpenGL
vie the platforms OpenGL binding layer. This (blindly) updates all the
backends to call this new function.

For now Cogl doesn't do anything with the notification but the intention
is to use it as part of a planned read-pixel optimization which will
need to reset some state at the start of each new frame.

a277b4091a x11: Hide all private symbols
The x11 backend exposes a lot of symbols that are meant to only be used

0a869e0718 egl/x11: Defer X11-specific code to the X11 backend

ca7dc2f951 cogl-backend-egl: Chain up to the X11 backend init_events
Since c6493885c3 when building the EGL backend for eglx there was
no fallback in the init_events implementation so the X11 backend init
function would never get called. This was stopping it from receiving
any X events so a lot of things broke. It now just chains up.

This backend is a event backend that can be enabled for EGL (for now).

codes into key keysyms.

This commit only supports key events, more to follow.

5f181f7265 stage-window: tweak has_redraw_clips semantics
This tweaks the semantics of the has_redraw_clips vfunc so we can assume
that at the start of a new frame there is an implied, initial,
redraw_clip that clips everything (i.e. nothing would be redrawn) so in
that case we would expect the has_redraw_clips vfunc to return True at
the start of a new frame for backends that support clipping.

Previously there was an ambiguity when this function returned False
since it could either mean a full screen redraw had been queued or it
could mean that the clip state wasn't yet initialized for that frame.
This would result in _clutter_stage_has_full_redraw_queued() returning
True at the start of a new frame even before any actors have been
updated, which in turn meant we would incorrectly ignore queue_redraw
requests for actors, believing them to be redundant.

a5c30398df egl: Adds support for clipped redraws

redraw the entire stage for small updates.

b499696d83 Use paint volumes to do automatic culling
This uses actor paint volumes to perform culling during
clutter_actor_paint.

When performing a clipped redraw (because only a few localized actors
changed) then as we traverse the scenegraph painting the actors we can
now ignore actors that don't intersect the clip region. Early testing
shows this can have a big performance benefit; e.g. 100% fps improvement
for test-state with culling enabled and we hope that there are even much
more compelling examples than that in the real world,

Most Clutter applications are 2Dish interfaces and have quite a lot of
actors that get continuously painted when anything is animated. The
dynamic actors are often localized to an area of user focus though so
with culling we can completely avoid painting any of the static actors
outside the current clip region.

Obviously the cost of culling has to be offset against the cost of
painting to determine if it's a win, but our (limited) testing suggests
it should be a win for most applications.

Note: we hope we will be able to also bring another performance bump
from culling with another iteration - hopefully in the 1.6 cycle - to
avoid doing the culling in screen space and instead do it in the stage's
model space. This will hopefully let us minimize the cost of
transforming the actor volumes for culling.

3540d222e1 paint volumes: another pass at the design
This is a fairly extensive second pass at exposing paint volumes for
actors.

The API has changed to allow clutter_actor_get_paint_volume to fail
since there are times - such as when an actor isn't a descendent of the
stage - when the volume can't be determined. Another example is when
something has connected to the "paint" signal of the actor and we simply
have no way of knowing what might be drawn in that handler.

The API has also be changed to return a const ClutterPaintVolume pointer
(transfer none) so we can avoid having to dynamically allocate the
volumes in the most common/performance critical code paths. Profiling was
showing the slice allocation of volumes taking about 1% of an apps time,
for some fairly basic tests. Most volumes can now simply be allocated on
the stack; for clutter_actor_get_paint_volume we return a pointer to
&priv->paint_volume and if we need a more dynamic allocation there is
now a _clutter_stage_paint_volume_stack_allocate() mechanism which lets
us allocate data which expires at the start of the next frame.

The API has been extended to make it easier to implement
get_paint_volume for containers by using
clutter_actor_get_transformed_paint_volume and
clutter_paint_volume_union. The first allows you to query the paint
volume of a child but transformed into parent actor coordinates. The
second lets you combine volumes together so you can union all the
volumes for a container's children and report that as the container's
own volume.

The representation of paint volumes has been updated to consider that
2D actors are the most common.

The effect apis, clutter-texture and clutter-group have been update
accordingly.

8dd8fbdbdf build: Start moving to a non-recursive layout
*** WARNING: THIS COMMIT CHANGES THE BUILD ***

Do not recurse into the backend directories to build private, internal
libraries.

We only recurse from clutter/ into the cogl sub-directory; from there,
we don't recurse any further. All the backend-specific code in Cogl and
Clutter is compiled conditionally depending on the macros defined by the
configure script.

We still recurse from the top-level directory into doc, clutter and
tests, because gtk-doc and tests do not deal nicely with non-recursive
layouts.

This change makes Clutter compile slightly faster, and cleans up the
build system, especially when dealing with introspection data.

Ideally, we also want to make Cogl part of the top-level build, so that
we can finally drop the sed trick to change the shared library from the
GIR before compiling it.

Currently disabled:

  ‣ OSX backend
  ‣ Fruity backend

Currently enabled but untested:

  ‣ EGL backend
  ‣ Windows backend

• Use the public COGL_HAS_GLES[12] define instead of the HAVE_COGL_*
   ones which are private and defined in config.h,
 • Install clutter-egl-headers.h which is needed by clutter-egl.h,
 • Remove clutter-stage.h as it's uneeded and does not work since the
   single clutter.h include policy,
 • Install the egl headers into their own egl directory as the x11 and
   glx backends do. The include should then be <clutter/egl/clutter-egl.h>,
   so document it. It does not really break anything as nobody could
   have used those broken headers.

e1e5db0032 cex100: Add a Clutter EGL backend for CE3100/CE4100 SoCs
Intel CE3100 and CE4100 SoCs are designed for TVs. They have separate
framebuffers that are blended together by a piece of hardware to make
the final output. The library that allows you to initialize and
configure those planes is called GDL. A EGL GDL winsys can then be
use with those planes as NativeWindowType to select which plane to use.

This patch adds a new ClutterBackendCex100 backend that can be
selected at compile time with the new --with-flavour=cex100 option.
