54d8aadf1d [cogl] Move the texture filters to be a property of the material layer
The texture filters are now a property of the material layer rather
than the texture object. Whenever a texture is painted with a material
it sets the filters on all of the GL textures in the Cogl texture. The
filter is cached so that it won't be changed unnecessarily.

The automatic mipmap generation has changed so that the mipmaps are
only generated when the texture is painted instead of every time the
data changes. Changing the texture sets a flag to mark that the
mipmaps are dirty. This works better if the FBO extension is available
because we can use glGenerateMipmap. If the extension is not available
it will temporarily enable automatic mipmap generation and reupload
the first pixel of each slice. This requires tracking the data for the
first pixel.

The COGL_TEXTURE_AUTO_MIPMAP flag has been replaced with
COGL_TEXTURE_NO_AUTO_MIPMAP so that it will default to
auto-mipmapping. The mipmap generation is now effectively free if you
are not using a mipmap filter mode so you would only want to disable
it if you had some special reason to generate your own mipmaps.

ClutterTexture no longer has to store its own copy of the filter
mode. Instead it stores it in the material and the property is
directly set and read from that. This fixes problems with the filters
getting out of sync when a cogl handle is set on the texture
directly. It also avoids the mess of having to rerealize the texture
if the filter quality changes to HIGH because Cogl will take of
generating the mipmaps if needed.

0d5e17ecd1 [units] Rework Units into logical distance value
Units as they have been implemented since Clutter 0.4 have always been
misdefined as "logical distance unit", while they were just pixels with
fractionary bits.

Units should be reworked to be opaque structures to hold a value and
its unit type, that can be then converted into pixels when Clutter needs
to paint or compute size requisitions and perform allocations.

The previous API should be completely removed to avoid collisions, and
a new type:

        ClutterUnits

should be added; the ability to install GObject properties using
ClutterUnits should be maintained.

9c7afe0c5b [timeline] Remove the concept of frames from timelines
Timelines no longer work in terms of a frame rate and a number of
frames but instead just have a duration in milliseconds. This better
matches the working of the master clock where if any timelines are
running it will redraw as fast as possible rather than limiting to the
lowest rated timeline.

Most applications will just create animations and expect them to
finish in a certain amount of time without caring about how many
frames are drawn. If a frame is going to be drawn it might as well
update all of the animations to some fraction of the total animation
rather than rounding to the nearest whole frame.

The 'frame_num' parameter of the new-frame signal is now 'msecs' which
is a number of milliseconds progressed along the
timeline. Applications should use clutter_timeline_get_progress
instead of the frame number.

Markers can now only be attached at a time value. The position is
stored in milliseconds rather than at a frame number.

test-timeline-smoothness and test-timeline-dup-frames have been
removed because they no longer make sense.

ffd5fb172b [docs] Rework the API reference version generation
Clutter copies the gtk-doc from the usual gtk+ template, and
has a version.xml.in containing only:

  @VERSION@

Without a newline at the end. Unfortunately, it appears that
autoconf has started adding a newline to the generated version.xml
which then is used as the payload for the "version" XML entity.

Instead of using a secondary file we can make configure generate
the whole clutter-docs.xml and cogl-docs.xml files from a template;
this way we also get the ability to substitute more autoconf variables
into the documentation -- if needs be.

67544f38d4 [cogl-vertex-buffer] Add cogl_vertex_buffer_indices_get_for_quads
This function can be used as an efficient way of drawing groups of
quads without using GL_QUADS. It generates a VBO containing the
indices needed to render using pairs of GL_TRIANGLES. The VBO is
globally cached so that it only needs to be uploaded whenever more
indices are requested than ever before.

4afe1e9a8b [actor] Add allocate_available_size()
The allocate_available_size() method is a convenience method in
the same spirit as allocate_preferred_size(). While the latter
will allocate the preferred size of an actor regardless of the
available size provided by the actor's parent -- and thus it's
suitable for simple fixed layout managers like ClutterGroup -- the
former will take into account the available size provided by the
parent and never allocate more than that; it is, thus, suitable
for simple fluid layout managers.

12c8ff8606 [cogl] Remove cogl_{create,destroy}_context from the public API
cogl_create_context is dealt with internally when _cogl_get_default context
is called, and cogl_destroy_context is currently never called.

It might be nicer later to get an object back when creating a context so
Cogl can support multiple contexts, so these functions are being removed
from the API until we get a chance to address context management properly.

For now cogl_destroy_context is still exported as _cogl_destroy_context so
Clutter could at least install a library deinit handler to call it.

6bb6686666 [cogl-vertex-buffers] Support putting index arrays into VBOS
It's now possible to add arrays of indices to a Cogl vertex buffer and
they will be put into an OpenGL vertex buffer object. Since it's quite
common for index arrays to be static it saves the OpenGL driver from
having to validate them repeatedly.

This changes the cogl_vertex_buffer_draw_elements API: It's no longer
possible to provide a pointer to an index array at draw time. So
cogl_vertex_buffer_draw_elements now takes an indices identifier that
should correspond to an idendifier returned when calling
cogl_vertex_buffer_add_indices ()

f322da3794 [material] Reduce the material API in preperation for releasing Clutter 1.0
There were a number of functions intended to support creating of new
primitives using materials, but at this point they aren't used outside of
Cogl so until someone has a usecase and we can get feedback on this
API, it's being removed before we release Clutter 1.0.

f28d5e481b [cogl-material] Removes all the API made redundant by the blend strings API
This removes the following API:
  cogl_material_set_blend_factors
  cogl_material_set_layer_combine_function
  cogl_material_set_layer_combine_arg_src
  cogl_material_set_layer_combine_arg_op

These were rather awkward to use, so since it's expected very few people are
using them at this point and it should be straight forward to switch over
to blend strings, the API is being removed before we release Clutter 1.0.

33994caa71 [cogl-material] Support string based blending and layer combine descriptions
Setting up layer combine functions and blend modes is very awkward to do
programatically.  This adds a parser for string based descriptions which are
more consise and readable.

E.g. a material layer combine function could now be given as:
  "RGBA = ADD (TEXTURE[A], PREVIOUS[RGB])"
or
  "RGB = REPLACE (PREVIOUS)"
  "A = MODULATE (PREVIOUS, TEXTURE)"

The simple syntax and grammar are only designed to expose standard fixed
function hardware, more advanced combining must be done with shaders.

This includes standalone documentation of blend strings covering the aspects
that are common to blending and texture combining, and adds documentation
with examples specific to the new cogl_material_set_blend() and
cogl_material_layer_set_combine() functions.

Note: The hope is to remove the now redundant bits of the material API
before 1.0

36cfb60307 [cogl] Remove the COGL{enum,int,uint} typedefs
COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.

The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.

The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.

cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.

a5cdfdfd87 [cogl-offscreen] Cleans up the cogl offscreen API and adds documentation
There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.

There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.

The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.

The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.

This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.

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.

Bug 1513 - Allow passing in ClutterPickMode to
           clutter_stage_get_actor_at_pos()

At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL

ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller
can specify CLUTTER_PICK_REACTIVE as a criteria.

216373047b [animation] Enhance consistency of the Animation API
The Animation API should follow this pattern:

  - functions with an Interval as part of the arguments should have
    "interval" inside their name, e.g.:

      clutter_animation_bind_interval
      clutter_animation_update_interval

  - functions dealing with property names should have "property"
    inside their name, e.g.:

      clutter_animation_has_property
      clutter_animation_unbind_property

    - unless -

  - functions dealing with a property and its value should not
    have any modifier, e.g.:

      clutter_animation_bind

The change from update_property() to update_interval() frees up
clutter_animation_update(), to be added at a later date.

89e3e3a4cc [animation] Add vector variants for ::animate()
Bug 1438 - Implicit Animation API could use animatev variants

The clutter_actor_animate* family of functions use va_lists to
handle the property/value pairs for the final state of the
animation.

Language bindings have problems with variadic arguments functions,
and usually prefer vector-based API which allow a greater level
of control and conversion from native data types.

For each variadic arguments function in the clutter_actor_animate*
family there should be a vector-based version that takes:

  - the number of property/value pairs
  - a constant array of constant strings
  - an array of GValues

Most of the internal implementation can be refactored from the
current one, thus both the var_args and the vector entry points
share a common implementation of the code; then, both versions
of the API are just loops over a list of arguments.

7d674db9d2 Clean up of the ClutterColor API
The ClutterColor API has some inconsistencies:

  - the string deserialization function does not match the rest of
    the conversion function naming policy; the naming should be:

        clutter_color_parse()   ->      clutter_color_from_string()

    and the first parameter should be the ClutterColor that will
    be set from the string, not the string itself (a GDK-ism).

  - the fixed point API should not be exposed, especially in the
    form of ClutterFixed values

  - the non-fixed point HLS conversion functions do not make any
    sense. The values returned should be:

      hue        := range [ 0, 360 ]
      luminance  := range [ 0,   1 ]
      saturation := range [ 0,   1 ]

    like the current fixed point API does. Returning a value in
    the [ 0, 255 ] range is completely useless

  - the clutter_color_equal() should be converted for its use inside
    a GHashTable; a clutter_color_hash() should be added as well

  - the second parameter of the clutter_color_shade() function should
    be the shading factor, not the result (another GDK-ism). this way
    the function call can be translated from this:

      color.shade(out result, factor)

    to the more natural:

      color.shade(factor, out result)

This somewhat large commit fixes all these issues and updates the
internal users of the API.

af0726480c [cogl-matrix] Documents that CoglMatrix members should be considered read only
In the future if we want to annotate matrices with internal flags, and add
caching of the inverse matrix then we need to ensure that all matrix
modifications are done by cogl_matrix API so we'd know when to dirty the
cache or update the flags.

This just adds documentation to that effect, and assuming the most likley
case where someone would try and directly write to matrix members would
probably be to load a constant matrix other than the identity matrix; I
renamed cogl_matrix_init_from_gl_matrix to cogl_matrix_init_from_array to
make it seem more general purpose.

03018f0c2a [Cogl] Renames cogl_paint_init to cogl_clear and adds a cogl_disable_fog function
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.

It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.

Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.

9cf02bfdb9 [text] Rename :alignment to :line-alignment
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.

Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.

3e68b23ea8 Merge branch 'scale-center'
Bug 1349 - Using the anchor point to set the scale center is messy

The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.

The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.

The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.

418fb995c8 Replace clutter_set_use_mipmapped_text with clutter_set_font_flags
The hope is that this function makes it easier to extend the font
settings with more flags without having to add a function for every
setting.

A new flag for enabling hinting has been added. If set, this changes
the font options on the global PangoContext and any newly created
PangoContexts. The options are only set if the flag is changed from
the default so it won't override any detailed setting chosen by the
backend.

134edac82c Bug 1361 - Unused ClutterStage::get_resolution() methods
The clutter_stage_get_resolution() and fixed-point API are just
shorthands for:

        clutter_backend_get_resolution (default_backend);

And as such do not fit at all in the ClutterStage class. The only
reason for their existence was the ClutterUnit conversion macros,
which have now been fixed to use the default backend through a
function call instead.

Thus, we can safely remove the stage entry points.

e338245827 Renames the mesh api to the "vertex buffer api".
This better reflects the fact that the api manages sets of vertex attributes,
and the attributes really have no implied form. It is only when you use the
attributes to draw that they become mesh like; when you specify how they should
be interpreted, e.g. as triangle lists or fans etc. This rename frees up the
term "mesh", which can later be applied to a concept slightly more fitting.
E.g. at some point it would be nice to have a higher level abstraction that
sits on top of cogl vertex buffers that adds the concept of faces. (Somthing
like Blender's mesh objects.) There have also been some discussions over
particle engines, and these can be defined in terms of emitter faces; so some
other kind of mesh abstraction might be usefull here.

3014d4ff8a Merge branch 'cogl-float'
Okey; to summarise the changes...

We have converted Clutter and Cogl over to using floating point internally
instead of 16.16 fixed, but we have maintained the cogl-fixed API as a
utility to applications in case they want to implement their own optimizations.

The Clutter API has not changed (though ClutterFixed and ClutterUnit are now
internally floats) but all Cogl entry points have been changed to accept floats
now instead of CoglFixed.

To summarise the rationale...

There have been a number of issues with using fixed point though out Clutter
and Cogl including: lack of precision, lack of range, excessive format
conversion (GPUs tend to work nativly with IEEE floats) and maintainability.
One of the main arguments for fixed point - performance - hasn't shown
itself to be serious in practice so far since we seem to be more limited
by GPU performance and making improvements regarding how we submit data to
OpenGL[ES]/the GPU has had a more significant impact.

Ref: The recent multiple rectangle queuing changes + the
cogl-texture-agressive-batching branch which show significant performance
gains, and that recent tests on the ipodtouch (ARM + MBX) also showed no
loss of performance running with floats.

So finally; please forgive the inevitable fallout, this is a far reaching
change. There are still a few known issues with the fixed to float
conversion but enough works for all our conformance tests to pass, and the
remaining issues hopefully wont be too tricky to solve. For reference two
tags will be available either side of this change: "cogl-fixed-end" and
"cogl-float-start"

74213e0ee3 [alpha] Allow registering alpha functions
In order to unify alpha functions and animation modes in ClutterAlpha
we should be able to register alpha functions and get a logical id
for them; the logical id will then be available to be used by
clutter_alpha_set_mode().

The registration requires API changes in ClutterAlpha constructors
and methods. It also provides the chance to shift ClutterAlpha
towards the use of animations modes only, and to alpha functions
as a convenience API for language bindings alone.

The multiple-texture-rectangle branch adds a new Cogl texture function
called cogl_texture_multiple_rectangles which is used to draw multiple
rectangles out of a texture using a single GL call. This is
significantly faster than drawing the rectangles with individual calls
on some platforms. The Pango renderer now uses this to speed up
rendering.

89e7552ca3 Bug 1172 - Disjoint paths and clip to path
* clutter/cogl/cogl-path.h:
	* clutter/cogl/common/cogl-primitives.c:
	* clutter/cogl/common/cogl-primitives.h:
	* clutter/cogl/gl/cogl-primitives.c:
	* clutter/cogl/gles/cogl-primitives.c: Changed the semantics of
	cogl_path_move_to. Previously this always started a new path but
	now it instead starts a new disjoint sub path. The path isn't
	cleared until you call either cogl_path_stroke, cogl_path_fill or
	cogl_path_new. There are also cogl_path_stroke_preserve and
	cogl_path_fill_preserve functions.

	* clutter/cogl/gl/cogl-context.c:
	* clutter/cogl/gl/cogl-context.h:
	* clutter/cogl/gles/cogl-context.c:
	* clutter/cogl/gles/cogl-context.h: Convert the path nodes array
	to a GArray.

	* clutter/cogl/gl/cogl-texture.c:
	* clutter/cogl/gles/cogl-texture.c: Call cogl_clip_ensure

	* clutter/cogl/common/cogl-clip-stack.c:
	* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
	stack code quite a bit to make it more maintainable.  Previously
	whenever you added a new clip it would go through a separate route
	to immediately intersect with the current clip and when you
	removed it again it would immediately rebuild the entire clip. Now
	when you add or remove a clip it doesn't do anything immediately
	but just sets a dirty flag instead.

	* clutter/cogl/gl/cogl.c:
	* clutter/cogl/gles/cogl.c: Taken away the code to intersect
	stencil clips when there is exactly one stencil bit. It won't work
	with path clips and I don't know of any platform that doesn't have
	eight or zero stencil bits. It needs at least three bits to
	intersect a path with an existing clip. cogl_features_init now
	just decides you don't have a stencil buffer at all if you have
	less than three bits.

	* clutter/cogl/cogl.h.in: New functions and documentation.

	* tests/interactive/test-clip.c: Replaced with a different test
	that lets you add and remove clips. The three different mouse
	buttons add clips in different shapes. This makes it easier to
	test multiple levels of clipping.

	* tests/interactive/test-cogl-primitives.c: Use
	cogl_path_stroke_preserve when using the same path again.

	* doc/reference/cogl/cogl-sections.txt: Document the new
	functions.

Bug 1014 - Clutter Animation API Improvements

	* clutter/Makefile.am:
	* clutter/clutter.h: Update the build

	* clutter/clutter-types.h: Add AnimationMode, an enumeration
	for easing functions.

	* clutter/clutter-alpha.[ch]: Add the :mode property to
	control the function bound to an Alpha instance using an
	enumeration value. Also add six new alpha functions:

		- ease-in, ease-out, ease-in-out
		- sine-in, sine-out, sine-in-out

	* clutter/clutter-deprecated.h: Deprecate the #defines for
	the alpha functions. They will be replaced by entries in the
	ClutterAnimationMode.

	* clutter/clutter-interval.[ch]: Add ClutterInterval, an
	object for defining, validating and computing an interval
	between two values.

	* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
	object responsible for animation the properties of a single
	actor along an interval of values. ClutterAnimation memory
	management is automatic. A simple wrapper method for
	ClutterActor is provided:

		clutter_actor_animate()

	which will create, or update, an animation for the passed
	actor.

	* clutter/clutter-debug.h:
	* clutter/clutter-main.c: Add a new 'animation' debug note.

	* clutter/clutter-script.c: Clean up the alpha functions
	whitelist, and add the new functions.

	* doc/reference/clutter/Makefile.am:
	* doc/reference/clutter/clutter-sections.txt: Update the
	API reference.

	* doc/reference/clutter/clutter-animation.xml: Renamed to
	doc/reference/clutter/clutter-animation-tutorial.xml to
	avoid clashes with the ClutterAnimation section.

	* doc/reference/clutter/clutter-docs.sgml: Renamed to
	doc/reference/clutter/clutter-docs.xml, as it was an XML
	file and not a SGML file.

	* tests/Makefile.am:
	* tests/interactive/Makefile.am:
	* tests/interactive/test-animation.c:
	* tests/interactive/test-easing.c: Add two tests for the
	new simple animation API and the easing functions.

	freeing CoglColor, for use of language bindings.

	* clutter/cogl/cogl.h.in:

	The Mesh API provides a means for submitting an extensible number of
	per vertex attributes to OpenGL in a way that doesn't require format
	conversions and so that the data can be mapped into the GPU (in vertex
	buffer objects) for - hopefully - fast re-use.

	There are a number of things we can potentially use this API for, but
	right now this just provides a foundation to build on. Please read
	the extensive list of TODO items in cogl-mesh.c for examples.

	Please refer to the cogl-mesh section in the reference manual for
	documentation of the API.

	* clutter/building-clutter.xml: Split the building instructions
	into its own file, for better maintainability.

	* clutter/clutter-animation.xml:
	* clutter/creating-behaviours.xml:
	* clutter/subclassing-ClutterActor.xml: Rename from SGML to XML;
	these were not SGML files anyway, but templates.

	* clutter/clutter-docs.sgml: Use XInclude instead of the ugly
	entities hack.

	* clutter/Makefile.am: Update the build.

Bug 989 - Add a search path for clutter script assets

	* clutter/clutter-script.h:
	* clutter/clutter-script.c:
	(clutter_script_finalize),
	(clutter_script_add_search_paths),
	(clutter_script_lookup_filename): Add the ability to define multiple
	search paths inside ClutterScript and to look up a specific filename
	inside those search paths. This is useful to define a set of
	directories where the assets for a UI definition are and still
	reference those assets by their name instead of the full path. (989,
	based on a patch by Matthew Allum)

	* clutter/clutter-texture.c:
	(clutter_texture_set_custom_property): Use the newly added
	clutter_script_lookup_filename() function.

778d421c11 * clutter/event-flow.png: fixed typo.
* clutter/event-flow.dia: added source for event-flow.png, this file
is not referred to in Makefile.am and thus not distributed in
tarballs.
