985518c601 color: Add named, global colors
Since EGA colors are apparently all the rage in other toolkits, Clutter
should not be left out. On top of the usual CGA/EGA palette the static
colors also include the Tango Icon palette, which at least is more
pleasant to the eye.

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

ef7f729c68 build: Re-instate profile builds
The profiling support was broken - probably during the restructuring of
the build environment, but I'm too lazy to bisect that.

The fix is trivial, and everything works as it should.

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.

* Use --pkg-export for Clutter-1.0.gir, since we want the .gir file to

* Drop the use of --pkg for dependencies; those come from the associated
  .gir files.  (Actually, --pkg is almost never needed)

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.

c260da79e3 effect: Add ShaderEffect
The ShaderEffect class is an abstract base type for shader-based
effects. GLSL-based effects should be implemented by sub-classing
ShaderEffect and overriding ActorMeta::set_actor() to set the source
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.

0057755854 profiling: Adds initial UProf support across clutter
UProf is a small library that aims to help applications/libraries provide
domain specific reports about performance.  It currently provides high
precision timer primitives (rdtsc on x86) and simple counters, the ability
to link statistics between optional components at runtime and makes report
generation easy.

This adds initial accounting for:
- Total mainloop time
- Painting
- Picking
- Layouting
- Idle time

The timing done by uprof is of wall clock time. It's not based on stochastic
samples we simply sample a counter at the start and end.  When dealing with
the complexities of GPU drivers and with various kinds of IO this form of
profiling can be quite enlightening as it will be able to represent where
your application is blocking unlike tools such as sysprof.

To enable uprof accounting you must configure Clutter with --enable-profile
and have uprof-0.2 installed from git://git.moblin.org/uprof

If you want to see a report of statistics when Clutter applications exit you
should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them.

Just a final word of caution; this stuff is new and the manual nature of
adding uprof instrumentation means it is prone to some errors when modifying
code.  This just means that when you question strange results don't rule out
a mistake in the instrumentation.  Obviously though we hope the benfits out
weigh e.g.  by focusing on very key stats and by having automatic reporting.

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.

1061ebeac9 [layout] Add BinLayout
A BinLayout is a simple layout manager that allocates a single cell,
providing alignment on both the horizontal and vertical axis.

If the container associated to the BinLayout has more than one child,
the preferred size returned by the layout manager will be as big as
the maximum of the children preferred sizes; the allocation will be
applied to all children - but it will still depend on each child
preferred size and the BinLayout horizontal and vertical alignment
properties.

The supported alignment properties are:

  * center: align the child by centering it
  * start: align the child at the top or left border of the layout
  * end: align the child at the bottom or right border of the layout
  * fill: expand the child to fill the size of the layout
  * fixed: let the child position itself

d6183e95e5 [layout] Add initial implementation of LayoutManager
The LayoutManager class is an abstract proxy for the size requesition
and size allocation process in ClutterActor.

A ClutterLayoutManager sub-class must implement get_preferred_width(),
get_preferred_height() and allocate(); a ClutterContainer using the
LayoutManager API will then proxy the corresponding Actor virtual
functions to the LayoutManager instance. This allows having a generic
"blank" ClutterActor sub-class, implementing the ClutterContainer
interface, which leaves only the layout management implementation to
the application developers.

6988744db7 [stage] Rework the Stage implementation class
Instead of using ClutterActor for the base class of the Stage
implementation we should extend the StageWindow interface with
the required bits (geometry, realization) and use a simple object
class.

This require a wee bit of changes across Backend, Stage and
StageWindow, even though it's mostly re-shuffling.

First of all, StageWindow should get new virtual functions:

  * geometry:
    - resize()
    - get_geometry()

  * realization
    - realize()
    - unrealize()

This covers all the bits that we use from ClutterActor currently
inside the stage implementations.

The ClutterBackend::create_stage() virtual function should create
a StageWindow, and not an Actor (it should always have been; the
fact that it returned an Actor was a leak of the black magic going
on underneath). Since we never guaranteed ABI compatibility for
the Backend class, this is not a problem.

Internally to ClutterStage we can finally drop the shenanigans of
setting/unsetting actor flags on the implementation: if the realization
succeeds, for instance, we set the REALIZED flag on the Stage and
we're done.

As an initial proof of concept, the X11 and GLX stage implementations
have been ported to the New World Order(tm) and show no regressions.

354fa437cd Update JSON-GLib dependency
Currently, Clutter depends on the internal copy of JSON-GLib for
the ClutterScript parser. This is done to allow building Clutter
on platforms that do not have the library installed on the system.

Just like we use the internal PNG/JPEG loader as a fallback in
case we don't have GdkPixbuf or CoreGraphics available, we should
use the internal copy of JSON-GLib only in case the system copy
is not present.

The change is simply to move the default for the --with-json
configure switch from "internal" to "check".

In order to allow stricter compliance, a third setting should
be present: "system", which fails if the system copy is not
available.

We should also change the introspection generation to avoid
breaking in case we require the installed Json-1.0.gir instead
of the generated ClutterJson.gir

ca305d2a40 [build] Search for Cogl GIR in the right place
Since we build the Cogl GIR inside /clutter/cogl we should be looking
there when building the Clutter GIR. Otherwise g-ir-scanner will look
inside the gir directory -- and if you never built Clutter before it
will error out.

d8aa6827ee Don't build Cogl.gir against installed Clutter library
Passing:

 --library=clutter-@CLUTTER_FLAVOUR@-@CLUTTER_API_VERSION@

to g-ir-scanner, when building Cogl was causing g-ir-scanner to
link the introspection program against the installed clutter library,
if it existed or fail otherwise. Instead copy the handling from
the json/ directory where we link against the convenience library
to scan, and do the generation of the typelib later in the
main clutter/directory.

678f99677f Use a single master "clock" to drive timelines
Currently, all timelines install a timeout inside the TimeoutPool
they share. Every time the main loop spins, all the timeouts are
updated. This, in turn, will usually lead to redraws being queued
on the stages.

This behaviour leads to the potential starvation of timelines and
to excessive redraws.

One lesson learned from the games developers is that the scenegraph
should be prepared in its entirety before the GL paint sequence is
initiated. This means making sure that every ::new-frame signal
handler is called before clutter_redraw() is invoked.

In order to do so a TimeoutPool is not enough: we need a master
clock. The clock will be responsible for advancing all the active
timelines created inside a scene, but only when the stage is
being redrawn.

The sequence is:

  + queue_redraw() is invoked on an actor and bubbles up
    to the stage

  + if no redraw() has already been scheduled, install an
    idle handler with a known priority

  + inside the idle handler:

    - advance the master clock, which will in turn advance
      every playing timeline by the amount of milliseconds
      elapsed since the last redraw; this will make every
      playing timeline emit the ::new-frame signal

    - queue a relayout

    - call the redraw() method of the backend

This way we trade multiple timeouts with a single frame source
that only runs if a timeline is playing and queues redraws on
the various stages.

a93a93d007 Count timeline frames using the FPS instead of an integer interval
Bug 1495 - Timelines run 4% short

Previously the timelines were timed by calculating the interval
between each frame stored as an integer number of milliseconds so some
precision is lost. For example, requesting 60 frames per second gets
converted to 16 ms per frame which is actually 62.5 frames per
second. This makes the timeline shorter by 4%.

This patch merges the common code for timing from the timeout pools
and frame sources into an internal clutter-timeout-interval file. This
stores the interval directly as the FPS and counts the number of
frames that have been reached instead of the elapsed time.

a3839296c4 [build] Various fixes for distcheck
The generation of the GObject introspection data has broken
the distcheck phase.

The location of the header and source files should always be
depending on the $(top_srcdir) and $(srcdir) variables,
respectively; the special handling of the COGL API inside the
GIR generation should also take those two variables into
account.

915d9ec7ca Split maintainer-flags from the compiler flags
The maintainer compiler flags we use trigger warnings and errors
in the autogenerated code that gtk-doc creates to scan the header
and source files. Since we cannot control that, and we must run
a distcheck with both --enable-gtk-doc and --enable-maintainer-flags
turned on, we need to use less-strict compiler flags when inside
the doc/reference subdirectories.

The way to do this is to split the maintainer compiler flags into
their own Makefile variable, called MAINTAINER_CFLAGS. The we
can use $(MAINTAINER_CFLAGS) in the INCLUDES or _CFLAGS sections
of each part of the source directories we wish to check with the
anal retentiveness suited for maintainers.

df7480090d Implements a generic ClutterActorClone that doesn't need fbos.
Many use cases for clonning an actor don't require running a shader on the
resulting clone image and so requiring FBOs in these cases is overkill and
in-efficient as it requires kicking and synchronizing a render for each clone.

This approach basically just uses the paint function of another actor to
implement the painting for the clone actor with some fiddling of the model-
view matrix to scale according to the different allocation box sizes of
each of the actors.

A simple unit test called test-actors2 was added for testing.

827c26757e Applied patch from bug #881
* clutter/clutter-frame-source.h: 
	* clutter/clutter-frame-source.c:
	New files that contain a replacement for g_timeout that try to
	cope with system delays.

	* clutter/Makefile.am: Added clutter-frame-source.{c,h}

	* clutter/clutter-timeline.c (timeout_add): Use a frame source
	instead of a g_timeout.

	* clutter/clutter-main.c (clutter_threads_add_frame_source_full)
	(clutter_threads_add_frame_source): New public functions to wrap a
	frame source and grab the Clutter mutex.

	* clutter/clutter-timeout-pool.c: Now calculates the timeout
	expiration times in the same way as a frame source does so that it
	counts time in frame intervals instead of setting the next
	expiration time as an offset from the current time.

	* clutter/json/Makefile.am:
	* clutter/json/*.[ch]: In-tree copy of JSON-GLib, a GLib-based
	JSON parser/generator library. We use it in-tree because we might

	* clutter/clutter.h:
	* clutter/clutter-script-private.h:
	* clutter/clutter-script.[ch]: ClutterScript, the scenegraph
	generator class. It parses JSON streams in form of buffers and

	* clutter/clutter-debug.h:
	* clutter/clutter-main.c: Add a "script" debug flag

	* clutter/Makefile.am: Build glue.

	* tests/Makefile.am:

	when GLib 2.14 has been released, we can use g_once_init_enter()

structures and enums, shared by different objects.

7f4b6b9c0e Add timeout pool source
A ClutterTimeoutPool is a source for the GLib main loop which pools
multiple timeout functions. The pool is always sorted so that the first
timeout to expire is also the first element of the pool; hence, extraction
is a constant time operation. This also makes the usage of multiple
timeouts at the same priority not compete for a timeslice of the main
loop, leading to starvation.

* clutter/clutter-container.[ch]: Add a generic actor container
	interface, for actors to implement without subclassing ClutterGroup.

	* clutter/clutter-group.[ch]: Make ClutterGroup implement the
	ClutterContainer interface, and deprecate the colliding methods.

	* clutter/clutter-layout.[ch]: Add extended layout interface.
	Actors and containers requiring or honouring complex layout
	management should implement this interface and provide at least
	one of the available layout types: width for height, height for
	width, natural size, iterative size request.

	* clutter/clutter-label.c: A ClutterLabel requires height for
	width layout management, so it implements the ClutterLayout
	interface.

	* clutter/Makefile.am: Add new files to the build.

	* tests/*.c:
	* examples/*.c: Update tests and examples code to use the
	new ClutterContainer API instead of ClutterGroup.

        Add initial 'cogl' implementation. 'cogl' is a simple abstration
        layer over GL and GL/ES used by clutter internally. It should
        eventually allow clutter applications to be run on both GL and GL/ES
        with just a recompile as well as provide more debugging and potentially
        profiling information for GL and GL/ES usage.

        This commit contains the initial GL implementation.
