16ed7677e0 Adds wayland-surface actor for wayland compositors
This adds a --enable-wayland-compositor configure option which will add
support for a ClutterWaylandSurface actor which can be used to aid in
writing Wayland compositors using Clutter by providing a ClutterActor to
represent Wayland client surfaces.

Notably this configure option isn't tied into any particular backend
since conceptually the compositor support can be used in conjunction
with any clutter backend that has corresponding Cogl support.

07c6f96cb4 wayland: Updates client side wayland support
This updates Wayland support in line with upstream changes to the Wayland
API and protocol.

This update means we no longer use the Cogl stub winsys so a lot of code
that had to manually interact with EGL and implement a swap_buffers
mechanism could be removed and instead we now depend on Cogl to handle
those things for us.

This update also adds an input device manager consistent with other
clutter backends.

Note: to use the client side "wayland" clutter backend you need to have
built Cogl with --enable-wayland-egl-platform. If Cogl has been built
with support for multiple winsys backends then you should run
applications with COGL_RENDERER=EGL in the environment.

a09bbffd92 Implement multi-backend support
The Clutter backend split is opaque enough that should allow us to just
build all possible backends inside the same shared object, and select
the wanted backend at initialization time.

This requires some work in the build system, as well as the
initialization code, to remove duplicate functions that might cause
conflicts at build and link time. We also need to defer all the checks
of the internal state of the platform-specific API to run-time type
checks.

9c102b7c51 Rework the interaction between the Cogl and GDK / X11 backends.
Previously, the Cogl backend was at times a subclass of the X11
backend, and at times a standalone one. Now it is the other way
round, with GDK and X11 backends providing the concrete classes,
layered on top of the generic Cogl backend. A new EglNative backend
was introduced for direct to framebuffer rendering. This greatly
simplifies the API design (at the expense of some casts needed)
and reduces the amount of #ifdefs, without duplicating code.

610a9c17ba Add a new GDK backend
This commit introduces a new flavour for Clutter, that uses GDK
for handling all window system specific interactions (except for
creating the cogl context, as cogl does not know about GDK), including
in particular events. This is not compatible with the X11 (glx)
flavour, and this is reflected by the different soname (libclutter-gdk-1.0.so),
as all X11 specific functions and classes are not available. If you
wish to be compatible, you should check for CLUTTER_WINDOWING_X11.
Other than that, this backend should be on feature parity with X11,
including XInput 2, XSettings and EMWH (with much, much less code)

It was already the intention that the ClutterGLXTexturePixmap API should

2d8083bab8 unify egl and glx backends as "cogl" backend
Since GLX and EGL are abstracted by Cogl the two backends are both
implementing everything using the Cogl API and they are almost
identical.

This updates the egl backend to support everything that the glx backend
supports. Now that EGL and GLX are abstracted by Cogl, the plan is that
we will squash the clutter-egl/glx backends into one. Since the EGL
backend in clutter can conditionally not depend on X11 we will use the
EGL backend as the starting point of our common backend.

7f78237ee5 clutter-actor: Add an 'offscreen-redirect' property
This adds a property which can be used to redirect the actor through
an FBO before painting so that it becomes flattened in an image. The
image can be used as a cache to avoid having to repaint the actor if
something unrelated in the scene changes. It can also be used to
implement correct opacity even if the actor has overlapping
primitives. The property is an enum that takes three values:

CLUTTER_OFFSCREEN_REDIRECT_NEVER: The default behaviour which is to
  never flatten the actor.

CLUTTER_OFFSCREEN_REDIRECT_ALWAYS: The actor is always redirected
  through an FBO.

CLUTTER_OFFSCREEN_REDIRECT_ONLY_FOR_OPACITY: The actor is only
  redirected through an FBO if the paint opacity is not 255. This
  value would be used if the actor wants correct opacity. It will
  avoid the overhead of using an FBO whenever the actor is fully
  opaque.

The property is implemented by installing a ClutterFlattenEffect.
ClutterFlattenEffect is a new internal class which subclasses
ClutterOffscreen to redirect the painting to an FBO. When
ClutterOffscreen paints, the effect sets an opacity override on the
actor so that the image will always contain the actor at full
opacity. The opacity is then applied to the resulting image before
painting it to the stage. This means the actor does not need to be
redrawn while the opacity is being animated.

The effect has a high internal priority so that it will always occur
before any other effects and it gets hidden from the application.

31da46c799 Adds the ability to build Cogl standalone
This adds an autogen.sh, configure.ac and build/autotool files etc under
clutter/cogl and makes some corresponding Makefile.am changes that make
it possible to build and install Cogl as a standalone library.

Some notable things about this are:
A standalone installation of Cogl installs 3 pkg-config files;
cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for
compatibility with what clutter installed though I'm not sure that
anything uses it so maybe we could remove it. cogl-1.0.pc is what
Clutter would use if it were updated to build against a standalone cogl
library. cogl-2.0.pc is what you would use if you were writing a
standalone Cogl application.

A standalone installation results in two libraries currently, libcogl.so
and libcogl-pango.so. Notably we don't include a major number in the
sonames because libcogl supports two major API versions; 1.x as used by
Clutter and the experimental 2.x API for standalone applications.
Parallel installation of later versions e.g. 3.x and beyond will be
supportable either with new sonames or if we can maintain ABI then we'll
continue to share libcogl.so.

The headers are similarly not installed into a directory with a major
version number since the same headers are shared to export the 1.x and
2.x APIs (The only difference is that cogl-2.0.pc ensures that
-DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of
later versions is not precluded though since we can either continue
sharing or later add a major version suffix.

The table we use for converting between keysyms and Unicode should be

This change moves the table to a source file, instead of an header; the

moved from clutter-event.c into this new source file. The declaration is
still in clutter-event.h, so we don't need to do anything special.

The event loop source code comes from the equivalent code in the Quartz

1b1e77b469 event/x11: Rework the way we translate X11 events
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.

The new design for handling X11 event translation works this way:

  - ClutterBackend::translate_event() has been added as the central
    point used by a ClutterBackend implementation to translate a
    native event into a ClutterEvent;

  - ClutterEventTranslator is a private interface that should be
    implemented by backend-specific objects, like stage
    implementations and ClutterDeviceManager sub-classes, and
    allows dealing with class-specific event translation;

  - ClutterStageX11 implements EventTranslator, and deals with the
    stage-relative X11 events coming from the X11 event source;

  - ClutterStageGLX overrides EventTranslator, in order to
    deal with the INTEL_GLX_swap_event extension, and it chains up
    to the X11 default implementation;

  - ClutterDeviceManagerX11 has been split into two separate classes,
    one that deals with core and (optionally) XI1 events, and the
    other that deals with XI2 events; the selection is done at run-time,
    since the core+XI1 and XI2 mechanisms are mutually exclusive.

All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to

94b905b9e1 build: Generate an instealled config header
Clutter has some platform-specific API that is accessible only if the
right backend has been compiled in. Third party applications that wish
to be portable across backends might want to use defines and other
pre-processor tricks to determine header inclusion and API usage.

While Clutter has an internal set of symbols it can use, third party
applications don't have the luxury of being able to access the config.h
generated by Clutter's configure script.

For this reason, Clutter should install a configuration header with a
series of namespaced defines that can be picked up by applications and
other third party code.

c6493885c3 evdev: First stab at an evdev backend
This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.

This commit only supports key events, more to follow.

ef5256ec25 evdev: Factor out the xkbcommon code from the wayland client backend
The wayland client code has support for translating raw linux input
device key codes coming from the wayland compositor into key symbols
thanks to libxkbcommon.

A backend directly listening to linux input devices (called evdev, just
like the Xorg one) could use exactly the same code for the translation,
so abstract it a bit in a separate file.

Since EGA colors are apparently all the rage in other toolkits, Clutter

pleasant to the eye.

Static colors are accessed through an enumeration by using
clutter_color_get_static(), or using the short-hand pre-processor

f5aeabadd5 Fixing cally.pc.in and moving include headers to previous directory
After commit 8dd8fbdb some errors appear if you try work directly
against cally:

 * cally.pc.in removed some elements. After install clutter, doing
   pkg-config --cflags cally-1.0
   fails due missing winsys

 * cally headers were moved from clutter-1.0/cally to
   clutter-1.0/clutter/cally.  Applications using it (yes I know,
   nobody is officially using it) would require to:
    * Change their include.
    * Add directly a dependency to cally, in order to use the cally.pc
      file with the correct directory include.

Note: Take into account that accessibility support still works (ie:
clutter_get_accessibility_enabled). This bug only prevents
applications to work directly against cally (ie: create a CallyActor
subclass)

66b0c1969c Remove the internal copy of JSON-GLib
The internal copy of JSON-GLib was meant to go away right after the 1.0
release, given that JSON-GLib was still young and relatively unknown.

Nowadays, many projects started depending on this little library, and
distributions ship it and keep it up to date.

Keeping a copy of JSON-GLib means keeping it up to date; unfortunately,
this would also imply updating the code not just for the API but for the
internal implementations.

Starting with the 1.2 release, Clutter preferably dependend on the
system copy; with the 1.4 release we stopped falling back automatically.
The 1.6 cycle finally removes the internal copy and requires a copy of
JSON-GLib installed on the target system in order to compile Clutter.

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

4ee05f8e21 keysyms: Update the macros to CLUTTER_KEY_*
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.

This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:

  - clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
  - clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*

The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.

This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.

d14e294d86 Add ClutterTableLayout, a layout showing children in rows and columns
A TableLayout is a layout manager that allocates its children in rows
and columns. Each child is assigned to a cell (or more if a cell span
is set).

The supported child properties are:

  • x-expand and y-expand: if this cell with try to allocate the
    available extra space for the table.
  • x-fill and y-fill: if the child will get all the space available in
    the cell.
  • x-align and y-align: if the child does not fill the cell, then
    where the child will be aligned inside the cell.
  • row-span and col-span: number of cells the child will allocate for
    itself.

Also, the TableLayout has row-spacing and col-spacing for specifying
the space in pixels between rows and between columns.

We also include a simple test of the layout manager, and the
documentation updates.

The TableLayout was implemented starting from MxTable and
ClutterBoxLayout.

code of the shader, and Effect::pre_paint() to update the uniform
values, if any.

The ShaderEffect has a generic API for sub-classes to set the values
of the uniforms defined by their shaders, and it uses the shader
types we defined for ClutterShader, to avoid re-inventing the wheel
every time.

c3ab32ae68 effect: Add OffscreenEffect
The OffscreenEffect class is meant to be used to implement Effect
sub-classes that create an offscreen framebuffer and redirect the
actor's paint sequence there. The OffscreenEffect is useful for
effects using fragment shaders.

Any shader-based effect being applied to an actor through an offscreen
buffer should be used before painting the resulting target material and
not for every actor. This means that doing:

       pre_paint: cogl_program_use(program)
                  set up offscreen buffer
           paint: [ actors ] → offscreen buffer → target material
      post_paint: paint target material
                  cogl_program_use(null)

Is not correct. Unfortunately, we cannot really do:

      post_paint: cogl_program_use(program)
                  paint target material
                  cogl_program_use(null)

Because the OffscreenEffect::post_paint() implementation also pops the
offscreen buffer and re-instates the previous framebuffer:

      post_paint: cogl_program_use(program)
                  change frame buffer ← ouch!
                  paint target material
                  cogl_program_use(null)

One way to fix it is to allow using the shader right before painting
the target material - which means adding a new virtual inside the
OffscreenEffect class vtable in additions to the ones defined by the
parent Effect class.

The newly-added paint_target() virtual allows the correct sequence of
actions by adding an entry point for sub-classes to wrap the "paint
target material" operation with custom code, in order to implement the
case above correctly as:

      post_paint: change frame buffer
                  cogl_program_use(program)
                  paint target material
                  cogl_program_use(null)

The added upside is that sub-classes of OffscreenEffect involving
shaders really just need to override the prepare() and paint_target()
virtuals, since the pre_paint() and post_paint() do all that's needed.

a86f1b45bb Add the ClutterEffect abstract class
ClutterEffect is an abstract class that should be used to apply effects
on generic actors.

The ClutterEffect class just defines what an effect should implement; it
could be defined as an interface, but we might want to add some default
behavior dependent on the internal state at a later point.

The effect API applies to any actor, so we need to provide a way to
assign an effect to an actor, and let ClutterActor call the Effect
methods during the paint sequence.

Once an effect is attached to an actor we will perform the paint in this
order:

  • Effect::pre_paint()
  • Actor::paint signal emission
  • Effect::post_paint()

Since an effect might collide with the Shader class, we either allow a
shader or an effect for the time being.

f6fce05ee9 action: Add ClickAction
ClickAction adds "clickable" semantics to an actor. It provides all
the business logic to emit a high-level "clicked" signal from the
various low-level signals inside ClutterActor.

4fd74e71e6 action: Add DragAction, an action implementing drag capabilities
DragAction is an Action sub-class that provides dragging capabilities to
any actor. DragAction has:

  • drag-begin, drag-motion and drag-end signals, relaying the event
    information like coordinates, button and modifiers to user code;

  • drag-threshold property, for delaying the drag start by a given
    amount of pixels;

  • drag-handle property, to allow using other actors as the drag
    handle.

  • drag-axis property, to allow constraining the dragging to a specific
    axis.

An interactive test demonstrating the various features is also provided.
